Today I decided to plug my multi effects pedal into the "effects loop, power amp in" plug. I noticed a more clear tone coming out of the amp, and that the amp's EQ does not work, but the EQ is worked from the pedal. I have also noticed the amp can get a lot louder then before. What exactly have I done? Have I turned my pedal into my pre/power amp? If so is it danergous to crank the volume knob up on my effects pedal?
