I've looked and looked, maybe overlooked and didn't find an answer to my question. I have an SVT 4-Pro and an 810E cab. I want to run 2 separate channels (from what I gather the 810E can do that) a clean one and a dirty one. Now, I am going through 7 pedals last of which is an MXR M80 bass DI. So my line consists of: Bass---Volume pedal---distortion---tremolo---envelope filter---flanger---delay---DI----Amp. Now, I want (or wish to) have everything BEFORE the DI in a clean Channel, and the DI alone as the dirty channel (the M80 has a distortion blend to it), all through my SVT 4-Pro. Is this at all possible? I bought an A-B switcher, per someones suggestion but I can't seem to figure out how to wire the damned thing. Anyone have any suggestions?? Is this even possible at all? Thanks in advance!
