I can't figure out why voltage readings on q2 collector are so high. around 8.5 volts. I followed the schematics and verified there was a 47k resistor and 100k trim pot in line before q2 collector. And I verified the pins of my q3. I have 3 different russian transistors, but I double checked...

I feel like I can't notice any noticeable change when sweeping the knob. The only substitution I made was for C3. I didn't have another 56pf, so I put a 48pf in there that measured 56pf on my capacitor meter. I did test the potentiometer. it measures at 20k and values change appropriately when...

Hi. I am trying to figure out what is going on here. Volume is much lower than clean signal going in. It sounds like gain and tone are working, as is the clipping diode switch (verified with a sound probe). The only substitution I made was 47pf capacitors for the 56pf. Although they both...

should both pairs of led's be lighting up? Right now only the top pair lights up on mine. Also it sounds to me like the tight switch is not doing anything. Should it be noticeable when the bass is cranked?

I am starting a new thread for this since I resolved the previous issue. The effected sound is pretty clean now, but I am not getting the amount of repeats that I think I should. I get like 3 repeats before they trail off. And I can't get anywhere near self-oscillation. I tried swapping pt2399...

I just finished my Dark Rift delay. Somehow any turning of the feedback knob beyond 0 causes a ton of hiss/static. I noticed other parts of circuit work (modulation, delay, etc) but are also a bit noisier than I think they should be. here is a clip of what it is doing. any thoughts of where...

I was planning on building a dual buffer for my pedal chain using the simple jfet buffer pcb's. When I was checking my first one for testing I noticed a considerable volume drop. I get sound. But it is way lower than just plugging in guitar direct. It did not sound like unity gain. When I took...

So I finally got my pedal working thanks to the folks on this forum. I didn't know if I should post this in troubleshooting or modifications. I have noticed there is a big jump in high end frequencies when the pedal is engaged. I am not sure if this is related to the resistor mod I did for R4...

So I have it kind of working. Lamp lights up and I get effected sound in chorus mode. But I am having these issues: Led's don't light up. I assumed the square pad was for positive (longer legs). I have yet to snip them. So I can always flip them if that is the issue. Vibrato mode is either so...
