This is Grot's G1000. It sounds great after replacing the filter caps, but it's still doing this even with all knobs on zero:
[FONT="]When he switches the chorus in & out seems to change the problem, that's where I'd start looking. [/FONT]
[FONT="]Never seen or heard one. Probably a bad chip in the chorus electronics.[/FONT]
From my amp tech:
Thanks guys. I'll take a look there.Interesting.
Does it sound good even with chorus active?
If it does, and since the noise is there even with the depth control on zero, I would guess that the chorus circuit itself is ok.
There is a part connected to the chorus switching which I assume is an analog switch chip.
Could there be noise injected via its control gate?
Is the capacitor connected from control gate to ground ok?
