Has anyone besides abfack actually built one of these? :scratch: Seems like the builder himself was concerned with instant doom after the schematic came out, but I'm thinking there is only one clone at the moment. Its a much larger undertaking than building a tube screamer clone so that will probab...

I know paying for the GGG PCB covers the licensing fee for the layout but I dont know if any of that goes to the original circuit designer. GGG may have handled that licensing at a flat rate or there may not be any at all.

Just to post an update to the first post in this thread — the pedals I was talking about were the older chrome models. The new Red Witch stuff has been redesigned to meet RoHS requirements and is extremely clean on the inside. None of my comments above apply to the current products.

Received one of these in a trade the other day and as usual I opened it up just to check the build quality and see what was what. The outside looks very professional. The inside... not so much. It doesn't take a genius to spot the General Guitar Gadgets BSIAB2 PCB inside this $168 distortion pedal....

Dont worry about the 'textbook values.' They didn't test them back then so you shouldn't stress about it too much now. Try socketing and swapping and see what you get out of it. I have a test rig with sockets that I use to match sets for my pedals and it should the difference between all the gain ra...

Maybe it's an old transistor, In my Phase 90 the PNP comes in that exact same package, don't know the classifier, though; maybe some manufacturers adopted the TO-92 later. And I could swear I've seen them in the flip-flop sections of some BOSS pedals, or BOSS knockoffs. Not sure. That package is ca...

If you reverse the polarity of all the polarized parts you can sub NPN germaniums right into this circuit. Its not NPN itself that causes the noise, its trying to wire up a PNP circuit as negative ground. OC140 are generally very high quality transistors so your build with them will likely be quiete...

Well you have guts and photos so its not really a request. Its the same layout as a meathead with some different values thrown in for the resistors and caps. At first glance the input cap is much larger than a meathead and the first transistor is definitely different. I have seen zetex mosfets in th...

Im looking for some AC125s if you've got 'em. Would be happy to buy a bunch or a set if you have them. Whatever works as long as they are viable for a tonebender. Thanks!

I have a Magnatone TC1 chassis with the vibrato circuit if you want a full set of varistors and some other original parts like transformers, etc...

Very cool to see there that close. After buying two Peaks (one for at the office, one at home) I haven't gone back to the RG Keen method. The RG Keen method is probably a little more accurate but with Germaniums and the amount of conditions that apply, I use the peak as a building block and my ears...

Time for an audio probe

Johan mentioned a few days ago that I should post this project. I have built and verified the board, although I have not had time to dig into it. EDIT FOR CLARITY: THIS DOCUMENT CONTAINS THE SCHEMATIC FROM THE DEGOOPING PROJECT. Project document: YellowShark.pdf The PCB image should be printed at 6...

What is that bitchin' technique he used for the solder lugs? They're like one piece inset to the Garolite? The Gold on Black looks positively regal inside the box! The designer for Moolon [and 1/2 owner] has brought an artistic aesthete to every pedal and guitar they fabricate. It leaves the the &q...

I dont have a pedal to take apart and help you or I would have. Maybe i'm way off base here, but when this particular project got going, didn't you ask abfackeln: "How about the polite request on the bottom of the pedal that asks that photos of the PCB not be posted on the internet..." :s...

Seems like the OP just built his clone and that was that. No more info. :( Think before you speak...... You've likely noticed that I've been quite active in another project, inside and outside of this forum. Also worked with kusi in fine-tuning the schematic (he did the real work); attempting to va...

That pulldown resistor wiring is actually pretty cool. I had never thought of doing it that way.

From the layout there it looks like three of the same circuit in parallel with different input and output caps to control the three frequencies that are boosted.
