So I'm new to pedals and effects but after getting the bug I'd like to start off by saying that I'm a littel bit hooked. I've also been purchasing lots of Source Audio pedals and would like to understand the midi function that is possible with them. I've seen those midi pedals, what are those? About a pedal board, I'm starting to look at certain pedal boards but want to know which one would be large enough to fit a SA BEF Pro, Multiwave Distortion (large pedal), Boss RC-20XL, SA Programmable EQ, and SA Phaser/Flanger and Expression pedal? Any ideas?
