Just perfboarded this one couple of hours ago, and debugging it (bad wiring around the bass pot).
I don't get much distortion out of it, only mild breakup, maybe because I'm using BF245A transistors... Would J201 really make that much difference?
Anyways I'm trying to get this sucker to fuzz out, and since I don't get much fuzz for now, I tried to boost the front end (with a flipster heh), and yes, it is promising! Nice breakup with loose lows...
I have ditched that treble cut network at the end, still thinking should I have put it anyways.
I'm trying to get this circuit to work nicely as a fuzz pedal, and so far, I think it has potential, that 68nF sure helps lows not to sound tight...
I have looked at various Orange schematics and while that Matamp Green is the thing I'm trying to err.. mimic, I have decided to alter Nelson's Orange Citrus in some things that I thought are important to the classic Green sound.
The tonestack is basically a pre 74 Orange type. Geert posted some unreadable matamp schem on the forums and it looked also that it has the same values in the tonestack. Also, unlike post 74 Oranges, the tonestack is after the second gain stage, if someone can enlighted me why there is a difference between that position or after the first gainstage, I would like to know heh...
Comments, inputs, appriciated...
edit:
Okay, I've debugged it, the tonestack works now great and the circuit has some mid gain fuzz tone, it sounds really good, any ideas how to get more distortion out of it? Ditch the 100k before the gain pot?
Nice!!
Why not replace Q4 with a FET mu-amp? Then add a fet buffer on the output. It's one less trimpot and I think it would deliver a cool sound. Sort of like adding power amp distortion on top of the preamp. Take the feedback network after the mu-amp.
I would use J201 if you wanted more fuzz especially Q1, Q2 + Q3.
Alternatively you could add clipping diodes after the boost section - that would surely get you into fuzz territory.
Looks to me like 3 and 4 could use gate bias resistors.
You mean like 1M to the ground from the gate of Q3?
Nelson, when you say mu-amp, you're referring to the two transistor connection like in Thor's Q3 and Q4?
(http://www.runoffgroove.com/thor.png)
Nah, I won't put diodes in it. I'll order tomorrow a batch of 100 J201's and when they arrive I'll try them, I have sockets installed, so easy change there. Later I'll try the muamp design at the end to hear how that sounds...
Why buffer after the muamp?

Yep, that's a mu-amp. You have to buffer afterwards because of the output impedence of the mu-amp.
Just use something like Jack Ormans Jfet Buffer or duplicate the output stage, you could also use an opamp buffer, you'll have the vref already from the mu-amp.
You have the 220K Gate bias for Q4 and the Bass pot for Q3.
By moving the tonestack to the second gain stage you are not allowing for as much recovery gain and therefore less fuzz.
I'm back from band practice, didn't test the Flipster, but I did try the Green Citrus...
Think I'll put the high cut network at the output of the circuit from other ROG type circuits, overall it didn't sound that much good as with my small amp, the big one is Hiwatt Custom 100 clone and I have treble on min to get rid of excessive treble and the Green Citrus was still too ear pearcing with highs...
Back to the drawing board heh... After the arrival of J201's, I'll try the muamp after the second gain stage...
Change the 10ú on the boost pot with a 22ú - 47u too.
I've updated the schematic, I still call it a V1.0 for now.
I have added the high pass filters from ROG type schems - sounds better this way, the excessive highs are cut, the 15k/2n2 networks, also the cap connected to the Boost pot is 22uF (didn't have 47uF, but I will place that one for sure).
The circuit works well, with BF245A's it's not a hi gainer, more of a low/mid distortion, the boost can be ommited, just use a 600ohm resistor instead of that 1k5 connected to the ground, and use 47uF in parallel to it - its the same thing as if you turn the boost pot all the way up.
If anyone is building this at the moment, try J201, please let me know how it sounds!

Sorry no perfboard layout yet! I improvised while perfin' so its a bit a mess to reverse the perf traces now heh.
It looks like there would be an effect on the bias of Q3 and Q4 since the feedback resistor has no cap in series with it. Is this the case?

Wouldn't this produce some nice gain sensitive assymetry on the output?
I've put a 68nF between the drain of Q4 and 15k as suggested - the circuit works better now, kinda "tighter", and boost function is not so dramatic as before, thanks for your input.
Hello everyone!
I'm back with the soundclips...
I built the multicab sim (http://www.diystompboxes.com/smfforum/index.php?topic=70427.0") from dschwartz so I figured I could do some fast clips of the green citrus...
Bear in mind that this is all BF245A unit for now, so there's not much gain from it...
Okay, here it is:
Guitar= Edwards goldtop 56' LP copy, mahogany 1pc body and neck, maple top, Seymour Duncan P90's (SP1-90 i think), 12-54 d'addario, guitar is tuned to C, the tuner is calibrated to 432hz but I haven't tuned my guitar since couple of days so it could be little off
Green Citrus = 68nF in feedback loop (drain of Q4 to 15k)
Multicab sim = have no clue how it's set up, I just turned the pots until I got pleasant audible results
Soundcard - EMU0404 PCI version
Guitar + Green Citrus + multicabsim + soundcard
gain is maxed on the green citrus for intro of the clip, later i turned it down, played some "clean" passages (i'm a bad player heh) and at the end, it's maxed out again, there is no software manipulatio, recorded, then amplified to 0db, call it normalize, i haven't used any software eq or compressors!
http://www.box.net/shared/ssa9jp8yro
Some people will recognize Sleep's Dopesmoker in the audio file, well, basically I'm trying to push this design to sound as close it can to the mentioned song heh..
And a quick Axis Face into whole thing clip (couldn't resist it!!)
fuzz max, vol 12oclock, citrus is set to clean
http://www.box.net/shared/y8eloh70g0
can't wait for the J201s to arrive...
oh! that sounds great, very dark!
by the way, nice work on the multicab, it sounds like it´s doing its job...
Quick repost...
clips!
http://www.box.net/shared/erntx428h1
guitar+green citrus+multicab sim+onboard soundcard
J201's in all positions now, and drain voltages are as follows:
Q1: D=4.05V
Q2: D=5.18V
Q3: D=4.61V
Q4: D=5.00V
I tuned the trimmers by ear, heh, there's alot of dirt coming from the circuit, I like it...
This is the final schematic for the Green Citrus V1
(http://i58.photobucket.com/albums/g249/bbozak/green-citrus2-1.gif)
Now I'll try the V2, first two gain stages will stay the same, after that, the muamp and a fet buffer afterwards, and then A/B test with the V1! :)
sounds cool!
rock'n'roll from doom! :icon_twisted:
That sounds awesome.
Heh thanks for the comments, I can't believe I managed to get it work from the first time, and the perfboard was done on the spot while soldering, I didn't have any template.... But flipster's perf layout could be used for guidance, it's not that much different...
yeah definitely sounds like doom, Pretty cool!
I really like the dark and doomy tone of this project of yours! Love the Orange amps, though i can't afford the real deal.. :)
Did you ever try this with the mu amp?
Does this look like the correct way to implement a mu amp?

nice design btw ... I might have to tackle this at some point in the future
What does the boost control ? just add "boost" or a kind of color like a "presence" or "contour" ?
I'll do a similar project , a cool Orange OTR preamp with something between 15V and 24V . Berfore that, I have to learn more stuff about FET bias. :-\
very cool stuff! i love the sound of the green amps, and this definitely gets close! i tried to get a similar tone out of ge trannies with a circuit i made called the Toecutter. it's written up on the blog in my sig. i'm going to have to give this a shot one of these days for sure. have you thought of biasing the FETs from the source?
Hi folks,
Sorry to bump such an old thread. I'm about to build this pedal with some mods in order to use it as a preamp. Let's say I replace Q4 with an SRPP stage which has low output impedance (good for driving a chipamp-based power amp). Would the "boost" function design affect in any way the low output impedance capability of the SRPP?
Thanks in advance.
Look at what the "boost" pot does. It bypasses Q3's source resistor (which reduces degenerative source feedback for that transistor; increases gain), and also cuts the signal coming through the 15k/68n from Q4's drain. This is a negative feedback path, so reducing it increases the gain for the Q3/Q4 pair.
One handy thing about negative feedback is it reduces output impedance, so the dynamic output Z of Q4 is actually lower than the DC resistance of the drain resistor might suggest. The more the gain pot is turned up, however, the less negative feedback and the higher the output Z becomes. Using another active device (be it SRPP or a source follower) at this point will increase the overall gain and drive the output lowpass filtering more ideally (note I used the word "ideally" rather than "better," as this is a distortion circuit and tone is subjective).
Additionally, if you want low output Z of the effect as a whole, the best place for a buffer would be after the output volume pot. The lowpass sections and volume pot contribute to a rather high overall output impedance regardless of the output Z of Q4.
OK, then a regular mu-amp stage will do just fine. I'll put a source follower after the master volume pot.
Thanks for the response.
Hah I passed this over before ,cause it didnt click "Orange Citrus" I was thinking OS clone :icon_redface:
That last soundclip sound fantastic !!!!
Love the Sabbath at the end,nails that dark tone.I think its definetly worth building at some point.
I added this to my ever growing folder of amp sims, :icon_cool:
Ya know I still think the FET emulations (alot of them at least) sound better than the digi amp sims in the popular software choices.
For instance that sounds much better than an Orange Citrus amp sim with the Orange cab sim,in a rather pricy software (I had the demo) I tried last month.
Heh can't believe this thread is still alive ;)
Haven't built fet emulators since this one, but i'm intrigued to try this "orange" type of circuit with muamps, having seen and heard catalinbread's dirty little secret - i'm conviced that muamps could work even better, and not to mention there's no need for trimpots...
Also - the bass/treble tonestack is cute, but if you ask me, I'm in for a single knob tonestack, I remember some time ago - I was looking at the bigg muff tonestack and with a help of duncan tonestack calculator it was possible to get a similar curve when bmp tone pot was in center position - similar to bass and treble crancked all the way on the baxandall...
Gain, Tone, Volume (boost omitted as I mentioned in an earlier post) - it would be a nice distortion pedal in the end. Maybe a switch to change the voicing of the tonestack...
Anyone care to dig into this? I'm kind of lazy, but could put up a schem in a couple of days... ;)
Longtime lurker, first post, and bringing this topic back from the grave! I know there was some talk about output buffers and SRPP's but I'd like to run this with a +24V supply with possibly an output to feed a slave amp. For starters, what components would have to be changed or added for +24V operation? I was planning on building a prototype with the values from the Orange AD200B V3 preamp schematic to make it more suitable for bass guitar.
Standout bass-fringe tone !
Deep dark and doomy clips are often accompanied by harsh harmonic nodes that are just too 'sharp' and fast for the curvy and slow bassy-source [harshness appears]...generally bassy-distortion seems to go 'just so far' into harmonic generation before the harsh-edges begin to surface, this sounds to go nice and deep into distortion while maintaining the ability to supress the raw, harsh edges. Jfets are cool. 2n5457's are fun too, falling somewhere between MPF102 and J201 ...average...gainwise [Jfets vary in bias needs/performance from fet to fet, even from the same part #'s and batch].

Just set the trimmers around 12V and you'll be fine. Also, avoid j201 transistors unless you want extreme distortion.
I would redesign the whole thing to the improved Fetzer Valve specs, though. Far more realistic for a preamp.
Thanks for the responses guys. I realize it will be a little over the top distortion/fuzz wize but to fix that I could add a low pass filter on the output. I was floored by the sound clips, so figured this would work for bass too. I want this pedal to have the ability to go from a nice overdrive all the way to a dark doomy sludge tone while maintaning low end.
Sorry for bringing this topic 2 years to the front!
I'm back, and with a vengeance!
Unfortunately Orange Citrus got lost in the drawer somewhere and I'm about to rebuild it once again, and this time I'll try to use it with a proper tube amplifier to get maximum results.
I own two Laney's (one GH100L and one VH100R), and I plan to drive the poweramp of one of these with the Orange Citrus MK2, hopefully it'll have enough output to push it, if not, maybe I should try with some sort of boost after the last gain stage?
Anyways, I'll start perfboarding it these days and hopefully put into full test in the next two weeks! Will post sound clips and photos too!
Cheers!
B.
Good to hear Branimir. I successfully built MKII but had some issues with output volume, oscillations, and now it doesn't work....there's 6v DC on the output volume pot, traced the entire circuit, replaced pots, caps, and transistors...oh well. As soon as I'm back from tour I'll give it another go! :icon_twisted:

I have the layout in Bancika's DIY Layout creator, will share when I test it.
I will incorporate switchable hi-cut circuitry that will be located before master volume pot, so it will be possible to switch off the hi cuts that are just before the master volume pot.
Soundclips soon!
No clips yet, but I've tried it with a big amp.
Have tried directly to power amp in, bypassing totally the preamp and just using the 4x6L6 to push 4x12".
Off the bat I've noticed that the hi cut circuitry is not really needed in this type of application, as it brings down the output of the circuit too much and the treble pot loses it's usability.
There's plenty of gain on tap, especially with boost dimed. Tone controls are as in every Orange, quite limited and this is just a one-trick-pony preamp, delivering thick distorted, almost fuzzy tone.
In a couple of days I will test it with a 4xEL34 amp to see if it delivers true Orange fat tone, because with 6L6 it sounds a bit modern and dark, with not alot of mids, and I think it is capable of pushing the poweramp, at least with the gain and boost and vol pot turned all the way up... ;)
One thing that is missing from this design, that is sort of crucial and a totally cheap trick -> is the FAC control, which is just a switchable coupling cap between two gain stages. The circuit is bass heavy as to the point of saturating the next gain stage too much, with gain maxed and even bringing down the tone pot does not help much. Blocking distortion? Farting palm mutes? That's it. The FAC control would give the control to the coupling cap before 2nd gain stage, and therefore omitting the amount of low frequencies that are passed into the circuit. I imagine lowering the coupling cap (22nF for instance) before the second FET would solve the blocking distortion problem, and give the full range of the bass pot, for those who like to crank the bass all the way ;)
I did notice on my build that unity gain was almost at 3 o'clock on the volume pot. Maybe a mu-amp/makeup amplifier would help here to give some boost? The tone was absolutely crushing though!
I was thinking of a mosfet gain stage a'la Jack Orman's Mosfet booster (http://www.muzique.com/schem/mosfet.htm)
Low current consumption and low output impedance, I like it...but with that many extra components, looks like it would be a pain to implement into the circuit?
OK So after some mods and debugging, I finally got this going. I used the original layout and added a stock LPB-1 right after the output, you can see it on the right side of the board. I set 4.71v for each trimmer but the signal gets kinda gated starting around 11 o'clock via the Gain control. I was surprised when I turned up my amp and didn't get any crazy feedback....probably have to fine tune those trimmers by ear? Or use 12v or 16v supply? Anyways, tried this with my crappy MIM tele through a '71 Sunn Model T and a Sunn Coliseum Lead and was quite literally blown away with thick doomy sludge (hooked up FOUR 4x12's to the coliseum amp, 300 watts RMS @ 2 ohms! Thanks Branimir for this project/inspiration. Would anyone like to hear sound clips or need more info?

In my experience, linear pots work better as gain controls for this kind of emulators. Log pots feel too "slow" in variable voltage dividers like all these circuits use. That's why people sometimes put an extra resistor between lug 1 -of a log pot- and ground. Of course, that also means you're no longer able to set the gain to zero.
Ladies and gentlemen, I give you sound clips!
https://soundcloud.com/labyrinth_audio/sets/green-citrus-samples (https://soundcloud.com/labyrinth_audio/sets/green-citrus-samples)
Forgot to add some details:
Citrus settings were: Gain and volume @ 10'clock and Treble, Bass, and Boost controls were at noon. Towards the end of both clips, I cranked the gain up all the way.
Model T settings were: Both in, Normal @ 3, Brite @ 3, Master @ 3, Treble, Bass, Mid, and Presence @ 5.
Coliseum Lead settings were: Volume 2, Normal input, Hi & Lo Bass @ 4, Mid @ 3, and Treble @ 2
In the middle of the clips, I turned down my guitar (MIM Tele) volume and brought it up slowly so you can hear that biasing issue I have.
Generally it sounds good but it definitely needs some tweaking for less farty-ness and the gate-like sound.
Let me know what you guys think!
Hi guys!
I've done some modifications to the basic circuit.
I completely removed tonestack to increase gain, added Tone(Cut) control before the output stage.
I added FAC control(really helps to get tighter bass, but even at 220p it gives nice fat sound)
Also I channged some values and rearranged feedback circuit(to my ears it sound better now).
So, now it's some kind of "dopesmoker tone in a box"(especially with FAC set to 47n).
(http://cs425319.vk.me/v425319783/49c5/JGqhtFCnBtM.jpg)
I'll record some samples if you are interested. :)
justaddsomeecho Yea let's hear some clips! I haven't done anything with this circuit since I built it...Did you have any issues with a gated/compressed sound that I experienced on my build? Might have had something to do with the tonestack...Thanks
Hello,
I have built a silicone adaptation of this circuit, starting from the schematic posted by justaddsomeecho. The transistors are 2n3904 and were biased as in the amz silicone transistor booster:
http://www.muzique.com/schem/multi.htm
I have shared the layout and a soundsample :
https://drive.google.com/folderview?id=0B3HEK-5LrRCydUNNeGJNSnpiYjQ&usp=sharing
What I used in the recording: a telecaster clone with seymour duncan picups and a fender fm15r amp. The mic was a professional zoom recorder placed slightly off the cone.
I guess I can fiddle with the biasing on this circuit to make it sound better, but i've decided to try out a couple more variations and insist on the one that i like most:
- mosfet variant
- Silicone version but with muff like stages (testing with and without diodes)
- silicone version with bazz fuss type arrangements for the stages
- opamp version
Advice would be welcome, even retard-proof ones :)
And yeah, jfets are impossible to obtain at reasonable prices around here. :D
I can't find the sound sample. ???
Oops, my bad. Try again now.
Great. Sounds just like this:
Thanks! I'll post the mosfet version as soon as its ready - i think that one will sound even closer. :D

Sounds sick!! How's the low end and lower gain response? As I recall, my prototype was farty and pretty much unusable at lower gain settings. Thanks!
Holy crapola! Come on guys keep em coming!!! Damn both of your guys boxes sound so damn close to a good old 90s Green..
The fact that both of you guys did your clips with Teles is even better (my #1 nowadays is my stock Classic 60s tuned down to C#).
My GGG Fuzzface gets sorta in that area with my AC15C1 but man you guys just about NAILED it.
I gotta hear this thing through my Vox AND my JCM800 half stack!
Hurry up thursday cause thats when my tax return gets here!!! :)
Hello guys!
Here's demo of my first raw prototype(recorded with my Estang(pine esquire and mustang hybrid with japanese Fender Vintage-Tl pickup in bridge position) tuned to drop C , directly into me recording interface, then i ran it thru Amplitube 3 Fender Twin Reverb)
https://www.dropbox.com/s/1zpox5mtdy46e1p/OM.mp3 (https://www.dropbox.com/s/1zpox5mtdy46e1p/OM.mp3)
Sorry for sloppy playing.
I changed it a little bit after testing with several different guitars and amps. I'll record new demo(with real amp and cab) soon.
Anyway, it's really nice sounding pedal with both guitar and bass. Not only for stoner/doom stuff, it's pretty versatile(FAC knob does wonders).
Oh, and it cleans up really great with volume knob.
But I don't like how it sounds with fuzzes before it(maybe a bias mistake), it gets too compressed to my taste even at low gain settings.
Wow, nice to see peple are still preoccupied by this topic!
I finished the second version and it sounds a little better, but i think i'll try a new approach for the next versions. Unfortunately it will be a while untill then, since my workbench is packed for home renovation..
I'll post the results as soon as able.
Justaddsomeecho - cant hear your clip, it gets downloaded but the player says it cant be opened...
Thanks,
I recorded another clip with my modded Sound City amp, Fane Medusa speaker and Sennheiser e609 mic.
I'm currently using this pedal with my band at medium gain settiings for really fat 70s rock overdrive, works nice with different amp/cab setup.
I'm adding full range booster of Muff before it for some super heavy stuff.

Hi there,
I'm really interested in having a go at this and was just about to knock up something in Eagle but just wanted to know which sort of diode D1 was on your schematic?
The demo sounds great!
Cheers,
Graham
That's just a 1N400x diode.
Hey, any chance anyone here has one of these they'd be looking to sell? I've been looking for a Green/Matamp style pedal for a while, and this looks promising, but I know nothing of building my own pedals.
Wow!
Sorry for ressurecting this topic after 3 years, but I could not resist, so many people with different inputs and outtakes on this type of circuit, awesome!
I kind of forgot about this project, too many things going on in life, and as I get older I tend to build distortion pedals using this mantra: "More tone, from less components", and having 4 trimpots and 5 knobs it's just too much stuff to do, to many parameters to tweak, so I like what you all guys done with it!

Can you post a schematic of the circuit? On your Drive, you only have PCB and layout, and the .diy file is also just the layout with the pcb.
Also, have you tried the mosfet and opamp versions?
Wish I had a better track of what I was doing with this and other circuits... Since most of them are desoldered, doing them again from scratch - I can't remember what I changed and why, heh.
