    Hi all,

    I tried to solve my problem alone, but i did not find why i have this buzz. That’s sure i did something wrong…

    It comes when I turn volume button (a100k pot) even if I’m in bypass. When effect is on, compressor is working but with that buzz.

    You can see pictures and a short video (listen at low volume) to understand what’s wrong.

    Thank you, for your help

    fr4nk – look closely at the output wires on the PCB – they are currently connected backwards. The blue wire on the output side needs to be connected to the pad with the ‘T” next to it. Just switch the blue & green wires where they connect to the output side of the PCB and all should be good.

    Ho noo, once again.

    Ok, I just machinaly plugged the output like where the “t” point was shown in the input.. Sorry.

    I’ll think about it when i’ll plug my other pcb. (Ratt Delux is at this step :-))

    Thank you again Cybercow
