I recently picked up a Pittbull Classic (Model G-100-CL, Serial CLD940202) that has some issues with the boost switches on both the clean and dirty channel. The boost is not enabled when either the switch is pushed in or out, however the boost is temporarily enabled when the switch is partially pushed in.
I’ve been trying to make sense of what’s going from the top of the board but it’s obviously challenging with no schematic. My wild guess would’ve been an LDR issue but it seems like the two boosts buttons might not even be impacting the same LDR?
Any pointers on what the cause might be?
