In a recent quest to make the loudest rudest distortion as simply as possible I came back to my favorite chip ever: the 386.
Here are two of them cascaded. No silly tone knob because Nigel would have just sneered at that. Two gain controls, on volume knob, and loads of sustain.
(http://www.beavisaudio.com/Projects/tufnel/tufnelV1_Schematic.gif)
And yes, it does go to 11.
:)
Nigel would be proud.
Can you describe the sound (other than loud :icon_biggrin:)
john
hahaha this is sooo cool!!
Dude, the two gain controls is total Spinal Tap, cause that way it can get even louder.
I'd imagine this one could induce some good eardrum distortion aswell ;)
Zach
...when you need the extra push over the cliff.
I love 386 distortions but I must ask...
1. can the chips take it (i.e. won't burn out)?
2. what does it sound like? Do you get anything other than noise?
The 386 chips are fine as long as you run them at their rated voltage. Of course the output is quite loud so I'll have to measure it before I actually turn it up to 11. :)
It sounds really really good. Great distortion with loads of sustain. Both U1 and U2 are stabilized using standard datasheet tricks. R4 and C7 tame the output of U1 a bit to keep it from oscillating.
Even on the breadboard it is *fairly* quiet, so I would expect that a clean build in an enclosure would yield a very workable pedal.
Tonight I'll add a switch to go between the existing C9 part and a 220uf electro. The idea being that with that switch I can go from distortion pedal to double ruby amp ...
I hasten to remind you that the zone where the gain is applied in the 386 can be determined simply by sticking a cap in series with the 1k gain pot. Normally, we are used to the pin 1-8 path being bridged by either a pot, or a fixed resistor, or a pot and large value cap (10uf). replace that cap with a smaller value (e.g., .047uf or .01uf) and the gain is applied only in the mids or upper frequencies. It works a bit like emitter caps.

It works a bit like emitter caps.
In previous builds, I added tone stacks after the 386, such as in Aron's 'super' version of the Smash Drive. I also breadboarded the krank distortion pedal that uses a similar tone stack at the end, albeit a poor one. There is also the trick of inserting a filter between the output of the chip and feedback pin 1 (ala the Bass Boost idea in the datasheet example).
In the end, tone shaping seemed to be so not part of the Tufnel philosophy.
Good point nonetheless!
Once one has built this, are they allowed to let anyone look at, or even touch it? :icon_smile:

Do I need a special pot that goes to "11" ?
I think you need to change the pots to 1K1, so that they can go to 11. ::)
if you want a tonestack i strongly recommend a baxandall type..they just rock!!
...wos rong wif sexy?
I often find myself wanting to play a bit, set my guitar down and go for a bite but still have my guitar sustain while I'm away. Is that possible with this pedal? If so, I'll take two and run them in series. That way, it'll go to 22 ;D
Will there be a VU meter on the box? I think one might be needed to show just how loud '11' is.
Maybe you could play 'Stonehenge' on it with the dancing people. That way it would also go to 'Elven'. :icon_eek:
...sorry, really really sorry...
Well if there are only two knobs, one should be labelled Love, and the other should be labelled Pump. The player has to supply the licks.
I can see this thread going in a different direction really quick....
You could build a special Artie Fufkin model and label the controls 'Kick' and 'My A$$'.

That looks cool!
I just finished an overdrive with a 386, based on the smash drive. It's kind of a cross between a Mozart and a Bach. Sort of a...."moch".
(Yeah, it comes off much better spoken than written.)
Maybe if it was done in "doubley"....

So, the official name is "Lick My Love Pump: right? lol :D
Man, I need to watch that one again soon.
And of course, there needs to be one unlabelled knob that you can't touch. In fact don't even look at it.
BTW did anyone here ever manage to buy some of those Tufnel volume knobs that I think DiMarzio sold in the 80's that really DID go up to 11? I wonder if they still make those.

[Imitating Nigel's accent]
Exactly.
Ya gotta love the first customer review there: "I was looking for a knob that made my guitar louder, and I found it with this Dimarzio knob. When I need that little kick over the edge, I can just turn my guitar up to 11, one louder than 10. I love this knob. I also put it as my tone knobs to make the tone a little brighter. It changed my tone so much. It's 1 louder, and 1 brighter." :icon_mrgreen: :icon_mrgreen:
Incidentally, as near as I can tell, the whole "11 thing" was a result of the first gliimerings of the vintage craze. Tweed and similar amps used legending that went from 1-12, continuing the old tradition of referring to positions in terms of "o'clock" positions. As interest in pre-1960 amps started to grow, there was a mystique developing about amps that "went to 12", in complete disregard of the fact that the 1-12 was simply paint on the chassis. And of course, with 11 being in between 10 (the newer legending on the Fender knobs) and 12, you know it just HAD to be better somehow.
makes you wonder...
do you think some one has made some kind of "extended range pot"?

Why not just make 10 louder?

I've got that problem licked on my two tweed amps; after 49 years, the numbers are pretty much rubbed off now. For all I know, they might go to
13.
The big question is how does this Tufnel distortion sound if you use a violin bow, or kick the guitar?

Just remember to make the 10 ohm resistors 2 watts or so, or you could have a smoking good time. :icon_mrgreen:

How about the .01uf on one of the gain sections and say a .2uf on the other gain section?
And hey, I've got 4 386 chips with nothing to use them for, how about using all 4 ? :) (my nearest neighbor is about a 1/4 mile away). Then I could go up to 22 instead of just 11 :)

For the last few nights I've been meaning to take the tufnel off the breadboard to move onto other more pressing projects. But I just kept thinking about it and the few remaining tweaks that would make it really nice.
The first problem is that the V1 circuit really is overly bright. I tweaked C4 from 47n to 4n7 and it seem to tame a bit of the shrillness. Second was a lack of a filter control. Even thought the spirit of the design was for unadulterated raunchy distortion, it seemed a lot less useful on the pedalboard without a filter. So I added a simple filter at the end--these are the new VR3 and C11 parts. It is an effective, if crude, tone control.
So here is v1.1 of the tufnel, a bit more useful and still tons of fun.
(http://www.beavisaudio.com/Projects/tufnel/Tufnel_Schematic_V1_1.gif)
Huh, very interesting circuit. I thought that the Smash Drive was intense enough, I can't imagine this one. Do any soundclips exist for this thing yet?

On the breadboard, the high-gain nature of the circuit (doh) causes real extreme noise and oscillation.
I'm committing it to protoboard tonight, so hopefully that will solve some of the noise issues and I'll do a vid soon.

Ninja parts are the new mojo parts.
Inductor/Choke I would guess.
Although there was talk of a resistor with a lot of current so maybe a homespun wire wound 10ohm?

The awesomeness, it is total. Are those metal letters?
Every time I think, 'I don't need any more distortion/fuzz/overdrive pedals.' something like this comes along and makes a mockery of my newly-found free will.
Yes on the metal letters, not sure on the dimarzios....
High gain circuits are a b**ch to stabilize. Might have to slash grounds and make them meet far away, decouple with RC networks, good luck.

Too bad no one makes wee tiny eight ball knobs. As I recall, Nigel has a guitar with an eight ball on the end of the whammy bar...gear shift style. Those would make cool knobs and still be a nod to Mr. Tufnel.
A soundclip, please... ::)
I just made a sound sample at www.myspace.com/dissoluteideas1. Turn your speakers down some, this thing really does go to 11.
The clip begins w/ both gains at min, then the 1st gain only at max, then the second gain only at max, then both gains at max. Watch out, it gets VERY loud at the end because there is some sort of oscillation/hum going on when i'm not playing. If anyone has any ideas on that i'd appreciate some help! I wonder if it's because put both chips right next to each other... it's the worst when both gains are all the way up.
It also sounds like i have a ground issue, there's a constant hum that gets louder as the gains are turned up. I've checked all my grounds 3 times and even changed the filter cap because it motorboats when on full gain and there's only a small amount of signal coming in. That also might be due to my chip placement. Any ideas on getting rid of motorboating?
If i can get this oscillation issue figured out i might put in a clean boost section so i can use a blend pot for bass guitar. Some clipping diodes might be an option too, it would definitely help contain the output which as previously stated is REALLY LOUD!
Sound very nice...thx a lot!

Hey MK, it was one of the FKR (Four Knob Rat) prototypes I built. There is more info here:
http://www.beavisaudio.com/projects/FKR/
I was on the phone with Mark at OLCircuits.com and he mentioned the circuit, simply calling it "the f*cker." I said "Wha?!?" and then he explained it was Dan's FKR. As low-brow as I can be, I had never read it as anything other than "eff kay arr."
LOL. I finally gave up on the pretense of the eff kay arr and simply call it the f*ker now. So much easier.
Done!

What I learned:
1. Slamming one 386 into another is certainly over the top, and the two gain controls are fun, but it is still to raw. I think that a buffer at the input leading to a volume control before the first 386 would yield a more useful effect.
2. The output is just too hot for practical use. Drive any other pedal and it will clip the signal. I tried various voltage divider arrangements at the output but no real luck.
3. The output signal overpowers the "tone" control. Need to rethink that.
4. Epoxying metal letters on a box requires more patience than I have :)
5. This circuit really needs some type of high-pass filter at the front. Amplifying the full range of bass makes it muddy.
6. Having the "World's Loudest Stompbox" is certainly cool, until you realize that you can never turn it up past three.
Here's a vid so you can hear what it sounds like.

just got an idea dano...
devolt wah pedal.
would let you control the sound coming out of that analog delay pedal.
just mount the guts in a old crybaby and replace the 1/4 jacks with the power cable.
call it the Volt Masta :icon_lol: :P :icon_lol:
Cool pedal, but the sounds didn't really do it for me.
It would benefit from some low pass filtering.

That's the least of its troubles.

Btw, I like your noize video. Sounds like you were having fun. :icon_wink:
Whoa, those are some cool knobs (referring to your completed Tufnel). Where did you get those?

don't recall for sure but they should be on my knobapalooza page:

That's what she said.
Seriously though, I am a knob freak. I have boxes and boxes of them. My favorite part of building a pedal is when the enclosure is done and I can spend hours auditioning different knobs for that perfect aesthetic appeal.
I must say, you have the biggest selection of knobs I have ever seen. Pretty cool. :icon_cool:
386 sounds like TUBES
