Peavey 6505+ no tone controls on clean channel.

Post by InDecemberOfficial » Mon Mar 14, 2022 7:28 am

Bought a used 6505+ head at a very low price, seller claimed it had no issues, so yeah, sure enough it has.

Clean channel: EQ controls nor PRE gain make any difference to the tone/volume, even with PRE gain on 0. Signal is just clean guitar tone. POST gain works.
Switching to crunch channel doesn't work (I can hear the relay switching but tone remains clean).
Bright switch doesn't work.

So it's like the entire preampsection is bypassed.

Oh and lead Channel works normal, all good there. Any idea where to start? Thx
