I have a pedalboard that I haven’t used in a couple of months so got it out again. It didn’t work. I have a few boss, some true bypass, and a Hudson broadcast. Trying to find the cause I took everything apart to isolate and test. The Hudson worked as normal using all the different isolated outputs on my power supply (mxr) and a power supply direct to the mains, so I know my cables are ok and I feel confident the power supply is ok. When I individually tried the buffered boss pedals, both with the mxr supply and direct, I got no sound either when they were off or on. When I try the true bypass pedals in the same way I get sound from the amp when they are off but nothing when I switch them on. All the LEDs work and the boss rc1 looper even does its spinning LED thing as normal - just without sound. is it possible I’ve blown something in all the pedals with the exception of the Broadcast or am I missing something? any help would be appreciated.
