What else would you like to see PCB projects for?

Oh just to make the Flanger even more Complex (and crazier) I dug up these 3 Sound Clips by Mr.Giles for his Bounce Mod he did to an Electric Mistress... TZF Bouncing???

Hmm, so what's happening here, multiple LFOs?

It's from the Eventide Instant Flanger apparently, it's meant to immitate 'jiggling' of the tape as it recovers from being put into TZF i'm led to beleive.
But yeah, basically I think it's just additional LFOs (on the schematic I saw it just used a single LM324 and few passive parts to accomplish)

I can't find the right schematic at the moment, but here's it implemented on something else http://img.photobucket.com/albums/v317/StephenGiles/bnce_clock.gif

+1 A/DA Final Phase

[space_ryerson]

The Randall RG100ES.

You'd want to re-arrange that PCB a bit; maybe split the pre and power amps to separate boards. There's a well known problem with channel bleed on those amps. Granted, they can be fixed by moving two wires, but still. Also, RG answered a thread I started years ago with a bias mod that seemed really good. It was over my head at the time...perhaps it is time to revisit 

[olslick]

mutron octave divider and maestro parametric filter, please.

[tiges_ tendres]

mutron octave divider and maestro parametric filter, please.

Seconded!  Those are two that I dont believe have been all that well documented.

+1 A/DA Final Phase

Is a schematic available for this?

http://www.adadepot.com/adagear/gearpages/stompboxes/ADA-Final-Phase.htm Not easy to read really.
Apparently (according to the Re-Issue of this) The Distortion section didn't sound good so would probably need replacing with something else too.

Ok, interesting. I actually was playing around with something like this a while back, using the TAPLFO which outputs PWM. I was just doing a modified Phase 90, but using switched resistors instead of JFETs. Never got too far with it, but I could see this project happening, perhaps sooner than a TZF. Even though tap tempo is not of much importance to me with phasers, using the TAPLFO gives us some really nice waveforms, and a lot of versatility with low parts count. Using switched resistors means not having to match JFETs. So this is something I'm very much interested in. I would actually want to do a 12-stage version if that seems reasonable.

[jkokura]

It would be kinda cool to have 4 boards from Taylor all about Modulation with Tap tempo: Phase, Flange, Trem, Echo with Modulation...

Final Phase and TZF Flange would be cool.

Here's a demo of the A/DA Final Phase http://www.youtube.com/watch?v=-j9Uf_uiSc8 (Only one about as far as I know)
Although I suggested it, Since I started getting together a run of EHX Bad Stone boards (which I find a bit more musical than that demo after listening and useful with the vibrato option) i'm not so sure i'm so interested, I don't really feel the need for Tap Tempo Phaser either really.

I still vote for the TZF first and the Analog Delay would be nice (That could work with Tap Tempo like the Deluxe Memory Boy) also How about a True Stereo Chorus with all the bells and whistles on board Akin to a Rackmount one from the 80s sorta thing but in a Stompbox format... now that could be fun... Say... Speed, Depth, Delay, Mix, Level Knobs & Vibrato and LFO Speed Switches And of Course True Stereo Outputs, could be based off any of the Favourite Chorus builds, just all on board and snazzed up a bit.

[deadastronaut]

boogie type dist/para eq/chorus/delay....all in one...with a send/return to add effects in line (ater the eq)too...oh..and a/b switch..

greedy?...yes!

[oldschoolanalog]

Greedy?
Synthi HiFLi.  
Now that's greedy.

Just joking...
Does make a TZF flanger look simple by comparison, eh?

[Taylor]

I have no problem with monstrous, complicated designs. In fact I very much enjoy that stuff, and love a chance to learn new things. The only issue is whether enough people will be interested - if we could reasonably guess that lots of people wanted an all-in-one effect with specifically those effects in it, then I would do it. I don't think that's the case though.

Now the Hi-Fli.... hmm. It's interesting, but I'm not sure it does much that can't be done these days with a few separate pedals (just from quick research). The only really special thing there is the frequency shifter, but I wonder how they managed to get a frequency shifter along with everything else in that size box at that point in history? It can't be a full-on thing like a Bode, or I would expect it to take up that whole case by itself.

[Perrow]

I know there's been a lot of nice complex effects projects thrown into this thread, so I'll go off on a tangent.

I'd really like to see a smallish SS amp (5-10 watt, might even be a chip-amp for my sake) with integrated tone stack and gain/overdrive/dist/fuzz (call it what you want). If you'd really want to please me, throw in a foot switch option for clean/overdrive channels and maybe a line in option for practicing to mp3's. Just a nice small simple practice/effects testing amp a little more powerful and versatile than the Ruby or Noisy Cricket.

It feels like I've looked high and low for something like this and only found two or three that doesn't quite do the trick.

[Taylor]

Hmm, it's an interesting idea, but again it needs to be something that does not require messing with mains power or getting special transformers. If there is an amp like that that can be powered on a single-sided power supply, it might be something worth looking at. I do think there's some stuff like the TDA2030 chip that works this way. I was messing with it a couple of years ago but never got too far.

Would this do you? http://www.diystompboxes.com/smfforum/index.php?topic=86840.0

and

Ambitious, I like it.

Ambitious? I could do with an A/DA STD-1 PCB if you wanna go for ambitious  sadly, probably alot less interest in that one.

The Randall RG100ES.

I don't know if it's of interest to you but while i'm here... there was a PCB for a Mesa Rectifier Amp but converted to J-Fets like the Randall around somewhere, I have the files saved but the thread should still exist... both the same kinda High gain area.

If you can find those files I'd be in debt to you sir!

Did you get my PM?

[the3secondrule]

I've had a lot of fun doing the PCB projects for this forum. I know that I really enjoy building on manufactured PCBs with all the "pro" goodies, and from the emails I get I can tell that a lot of people feel the same way. I never thought it would make much difference, but since I've started working on these, my etching rig has been sitting lonely and unused for quite some time. 

Anyway, I was just curious what else you guys would like to see a PCB for. I do have some things cooking up, but other suggestions are greatly welcomed. I am still working on the tap tempo stereo delay, and I also have a clean analog octave down board (based on the Oc-2) that is near completion.

What else would you like to see?

Ibanez Flying Pan, or some sort of ring modulator would be neat!

[snufkin]

e&mm harmony generator
e&mm pitch to cv (although I already have this sitting half populated for the last 2 years )
cut down mutron biphase

[dmc777]

If we get it verified the TZF Electric Mistress (Or another Flanger... there's a schematic for a MN3007 MXR M117 By Fender3D which would make a great TZF Flanger I bet) All on one PCB Would be great to see.

A Stacked Chip Analog Delay of Some Description (Like a Memory Man but for V3205 or Those 8Pin BL3208s)

A Good Chorus Project would be nice too, not sure what kind though.

A/DA Final Phase? We had the Flanger...

A High Gain Distortion like the DieFet or Dr.Boogey with on board MAX1044 Doubler.

What he said. Although I'd like to have a blend/level control on the chorus and delay. Delay would be nice with tap tempo and expression pedal as well. I'd also like to some projects pcbs that are on Beavisaudio page if possible. Something like the trotsky and the crazy Rat he made.

An Acoustic Simulator Project like Mark Hammers Woody or the AC-2

That's my input, in order of preference.
