Im using a Metal Zone boss pedal. I plugged it in to my 65 watt Crate amp... no feedback. I plug it into my 100 watt carvin tube half stack... **** LOADS of feedback. same guitar, same cords, same settings. what could it be?
That the Carvin half stack is actually, like, 3 and a half times louder than the Crate amp?
maybe you have your volume up a lot higher on your halfstack?
even at about level 5... WAY more feedback than the Crate had on 10.
Turn it down? Drop the pedal?
