Good evening.
Currently working on the Son of Ben (Benson Preamp) pedal. I am not getting sound when the pedal is engaged - however, the LED is turning. Furthermore, I have built an audio probe, and it appears the signal drops when I reach C6 in the schematic.
To note:
Q1 Drain: 3.9
Q2 Drain: 4
Q3 Drain: 4.36
I am willing to concede that reflowing my joints will help in the problem; however, I’m clueless as to why or how the signal is dropping from C6. I’ve even gone so far as to replace the part/component under the guise that I was faulty. Despite my efforts, the pedal is still not functioning and no signal is passing through.

To note:
- I used jumpers for the dual gang pot because I get paranoid about having to troubleshoot and resolder parts.
- Utilized the SMD pre-soldered JFETS (J201) from PedalPCB. Did some weird jumpering on Q1 and Q2 and soldered in some pin headers for Q3. Not the most eloquent work but I am getting “voltages” on the Drain (see below).
