So I've done some further testing and here is what I found: for all these tests all knobs were at 12 o'clock for both channels and I also found that the level between the two sides was the same when switching between them. All dip switches off gives basically unity gain, turning on any of the...

Thanks both of you for the info! I checked the voltage split at R12 and R13 and it seemed like it was working just fine, so then I checked the voltages of the sockets and was getting 0V on pins 1, 2 and 4, about 2.3V on pin 3, about 4.7V on 5, 6, and 7, and then about 9.5V on pin 8 for both...

Bump

Built this a while ago and until recently it was working perfectly. The other day I noticed that the setting I usually use on my Paragon Mini was much lower and I wasn’t getting unity gain until about 2 o’clock on the level knob where before it was around noon if not a bit lower. voltage...

Update: I’ve got the pedal working beautifully. I shuffled around some different combos of transistors and settled on a combination I really dig. Getting about -0.9V on Q3 collector now. No more gating and much more sustain/feedback. Thanks again!

Thanks so much for this great info! I’ve measured Q3’s collector to be at around -1.9V with balance and sustain at max so it would appear that is the culprit. I’ll try swapping this out for a higher leak transistor and update the results.

I recently finished a build of the Gnat fuzz and I haven’t been able to get it to sustain or feedback in that classic Fripp style. The pedal seems to gate off my notes quite easily even when everything is cranked. Transistor hfe values are: Q1 - 67 Q2 - 92 Q3 - 106 I know the recommended value...

These pedals recently became somewhat more easy to find for a reasonable price, but I’d love to see a great DIY version of this pedal. I know the ICs are a little tricky to find sometimes though.
