My problem: everything about the pedal works very well and as expected (or unexpected) EXCEPT the gate pot changes nothing at all in the sound CCW or CW. Gate trimmer ditto, full CW or CCW, no change.
Checked continuity of everything from the transistor before the gate pot to the transistor after, and all is connected.
What I need help in understanding is whether I need to proceed further down the schematic to investigate what could be non-functioning in the gate control. Does the downstream bit with the LM258P and all that also affect the gate control? I am guessing so, since there is no trim anywhere else, and I'm guessing "Trim 2" refers to the Gate trim. I'm not super sure what I'm looking at, actually, in terms of understanding this big-ass complex circuit and what/how the subunits are delineated and work, particularly (and obviously) the gate control.
I am also assuming LPG refers to the Gate ("Low Pass Gate?" qu'est-ce que c'est?) so... it's important? LPG control from the LM258P and R29 connects where? To the LM13700N LPG control?
