I designed a PCB layout with @derringer’s mods. Works well sounds amazing. I had boards manufactured at PCBWay.com. Here’s my build. I milled this black powder coated enclosure. I had a few troubles getting the settings right I was trying a new bit.derringer wrote: ↑20 Jul 2012, 21:13and that's pretty much what I did for my superfuzz buildThaxt wrote:I think the 1N34A diodes - or the OA-90s - weaken this pedal's sound when they are direct to ground; the AMZ warp mod - placing a 10 K pot between diodes & ground - seems a key to getting both better volume & fuzz texture.
I've tried the stock configuration, & it does come off as way too weak...hissy & fuzzy, but (IMO) not a strong fuzz.
LED's as subs do tend to hit pretty hard, but the usual other diode subs can do wonders, & bring out the UVSF's innate, characteristic sounds.
Modding the midscoop is key too. Modding those 2 things can get you a whole 'nuther Superfuzz, meaning: in a good way.
The (overly?) scooped, meek & fizzy can become: WOW! The scoop is great for bass tho.
and it's been on my pedalboard around 3 years now, love this thing
I made one mistake C6 was connected to the collector of Q2 instead of the emitter . Was able get it working by putting C6 on the backside and bending the leads to make the proper connection.
The trimmers add a ranger sound that’s a nice bonus feature to have.
