I'm putting together a new pedal board and am wondering about loopers. I get the basic idea that by running effects on different loops you shorten the signal path and isolate effects from each other. On a board that has around 10 effects - wah/comp/3 o.d's/2 delays/trem - is it really useful or necessary to do this? It seems like many huge boards are looped and the smaller ones aren't. I was checking out Loopmaster's site and was wondering what's the difference between a 2 loop box and a 2 loop box with master bypass? If both loops are off, isn't the signal going straight to the amp? Also, when you have things in a loop, are the effects always on and the loop switch controls them? School me on this one, maybe I'm just looking for a way to spend some more jack and take up more room on my board?
