I'm wondering when it's important to use an effects loop of an amp. Right now I have everything in front of the amp with nothing in the loop, but I keep hearing that when you leave certain effects in the effects loop of an amp there is less tone suckage. And if so, what effects go in there? I know there's delay and modulation stuff, but is a Wah considered to be a modulation pedal? Also what's up with the looper pedals? Why do people use them instead of using the effects loop. I just need an answer cause this has been driving me crazy for a bit. Thanks!
