Hi! This isn't normal, right?
Peavey Delta Blues.
All knobs are down to zero, guitar is unplugged.
There is no hum only when knob is in extreme positions.
The pot works like it should - cutting treble like it supposed to. Any ideas what can it be?

| Not a clue. But you might try dosing it with Deoxit or replace the pot altogether. Sorry, that's all I've got. |

Sounds like 60 cycle hum. If it amplifies, it is probably time to change the power supply caps.

AHHH- Delta Blues 60 cycle hum ! Been down this road with this amp. Turns out it is the shielding on the power transformer which is more evident with the higher frequencies. I spoke with the PV guys about this years back and it had something to do with improper copper shielding / wrapping on the power transformers used on the Delta Blues . They offered to send me a new tranny at no cost but also said it may not be better than what I had. It drove me nuts- I sold the amp.
