Bout to vent...
I've been troubleshooting a pt2399 delay with a big muff tonestack. Custom build.
The blend does not go 100% wet despite it being a pot to pan between dry and wet signal. The pot measures continuity across rotation. There is a volume control directly coupled after.
Then the tone control acts like a volume control which goes to 0 on the treble side. I thought this could've been a shorted cap to GND but alas it is not. Pot measures continuity across range.
Perhaps most confusingly is that while the main delay can be muted via the tone control, I can still hear the repeats.
I've checked the DC voltages which are all fine.
I recycled the pots and some caps from other builds before.
I'm confounded to say the least. I'm wondering is there a point where it's better to start over from scratch?
