I got a Traynor YCV50B and i just picked up a TC Elelctronic Ditto Loop pedal. When i play through the pedal into the amp input the overdub i am doing cancels out the sound of the chord progression. My amp has an EFX loop input and output an I read about plugging the amp line out into the input of the looper and then plug the output of the looper back into the return jack of the amp. Is it really that simple?
Fx send - looper in - looper out - fx return. I have only a little experience with loopers, but thats the chain for an fx loop setup. What other pedals are you running?
