Ok so i have been trying to pin point this issue with my Peavey 3120 (still under warranty) before i send it out i want to verify that it is indeed a real issue and not me messing up something.
Alright so there are three channels,
Channel 1 = Clean
Channel 2 = Crunch
Channel 3 = Lead
So here is the problem, when i turn the "FX Loop" on via the pedal channel 2 and 3 get WAY louder, even with the send receive knobs only half way turned up (worse when they are all the way up), when the FX loops is turned off i can crank the power tube volume to 9 and the pre amp volume to 9 and it will get as loud as the power amp and pre amp volume on 3 and 5 with the FX loop on. Now this issue does not happen to channel 1 at all, only 2 / 3.
It annoying because i have to leave the FX loop on all the time to play with my band, am i doing something wrong or is there something wrong with the amp?
Some FX loops will have a gain or boost to them, mine does, but there is a knob to turn it up and down.
