If anyone were inclined to draft a vero layout for this it would be greatly appreciated! I altered the Tychobrahe layout which gets pretty close but there are still some significant differences that make me curious. The missing values can be plucked from Storyboardist's work at the link below. I tried to upload the image but wasn't able.
I was wondering about that but the PCB shows Fuzz pin 1 attached to nothing so I left it unattached. The cap shorting out I ignored! I mainly followed the PCB and perf board layouts because people have built from those and the pedal has worked.
HamishR, I studied your layout and the schematic closely before building it and it works fine. Positively VERIFIED. I didn't have any BC558s and used a 3906 with MPSA18s. It was little hot so I swapped to a 4402 and a pair of 3904s. Tried a 2N404A (130 Hfe) in Q1 which was cool and then a pair of MP38As in Q2 & Q3 with the 4402 in front. Its a cool circuit with loose, saturated lower register and bright, clear upper register notes. I love sludgy tones so this one's right up my alley. Thanks again for the layout!!!
Wow - yay! Thanks for testing it. I'm about to build it myself now. Here is a slightly updated version for anyone wanting to build it. I just got rid of some cuts which didn't need to be there and changed the transistor info according to what I could find out. So the original is fine - this one is a little more efficient. :-)
Built it today - just happened to have some BC560B and 2N3904 trannies. I would probably suggest a C1K for gain if you're using a Strat. I like this pedal - it's cool when goosing a mild OD too. Very squishy and oozy.
Thanks for the layout, it worked great. I built one using a 2N3906 and a pair of 2N3904s. I used the C1k like Hamish suggested and am thinking of adding a pregain pot. I was also wondering if adding a bias pot to one of the transistors would be of any use for some Velcro type fuzz. This is mainly because I don’t want to buy any new enclosures right now and I have a box with Jimi painted on it that would be perfect for housing this one but it has four pot holes drilled in it. That and I thought my silicon Sunface sounded pretty cool with it.
