Compared against my isosceles build my triangulum has very little boost available. Like I couldnt see using it less than maximum. Isosceles is INSANELY loud. The pedal also cuts far less bass than ISO in triangulum mode.
The potentiometer works without scratching or issues as does the footswitch and LED.
R1,R2,D1,D2,Q2 omitted. (100pf mounted underneath board for fit. not missing.)
The build looks fine even under magnification. I did notice the caps seem a bit “microphonic” near Q1 when tapped with a screwdriver. Not sure if that is normal.
I am not sure how to start debugging. I have checked the pin one voltages of the 7660 (9.12V) I am using and the opamp opa134. (30.0V)
Any help would be appreciated.
I am pretty stumped and trying to learn to properly debug so I can get to my shelf of non working builds. :/
(The labeling print on the 820R was smudged, value was confirmed with multimeter, NOT an incorrectly placed “20R”.)
