Is there a way or any info anyone may know about to bypass the effects loop in the Peavey Classic 50? I dont want to use a pot to set the level in the FX. I used all of my effects if any in the front door

From Classic 30 mods, which are similar to Classic 50 mods: "Once you are satisfied with the tuning and operation of the tone stack, you can add in the relay board as explained in detail later. The signal continues through the FX loop, which uses a transistor circuit to drive the FX Send jack. Fortunately for tube freaks, the audio signal is routed through the transistor only when the FX loop is used, which is a fair enough compromise because most FX processors use solid state components in the signal path anyway. With nothing plugged into the FX Return jack, the signal from V2B passes directly to V3A only through the 0.1uf coupling capacitor C31."

This may be a stupid question , but I'm going to ask anyway , if your going head into your amp , why do you need to disable the effects loop it should be inactive ?
