First I've searched, and found similiar posts, but not quite this exact dilemma. I'm struggling what to do here. My "secondary rig" consists of a KustomGroove 1200, BBE 362, Behringer MDX1400 compressor, rack tuner, rack power unit. I have a Sansamp BDDI and MXR M80 out front right now. I am considering the SA RBI rack unit which I would have to make room for. Question: Should I run the SA through the effects return-bypassing the pre, (no power amp "in" on the Kustom) or run the racked SA through the front input, keeping the 1200's pre in play which creates a problem hooking up my M80? I guess I could run the M80 to the SA, SA to the front input. (not convenient). I just want to make sure I could use the effects inputs on the RBI to keep the compressor and BBE in the loop. Option B: Sell the KG1200 and get a dedicated amp to use with the SA RBI pre... Option C: Get the RBI for my Ampeg rig (B4r) which has all the inputs needed and keep the pedals for the Kustom rig. I think if I sell the Kustom, and get a power amp, this rig may very well take over as my "A" rig over the Ampeg. Yes, a confusing post I know... but you are all smart enough to see past my rambling confusion right? Thanks.
