Not sure where to post this question, but here goes: My main project right now is a duo that uses rc50 loop stations to create layerd/textured music. I have a setup issue and i'm not sure where to turn for advice. The issue is this: If I run my bass directly into the amp, then through the effects loop into the rc50 and back, I cannot control the volume of something once it is looped because its returning directly into the power amp. I can run directly into the loopstation, then into the amp so that I can adjust volumes, but to keep in sinc we wear headphones from the rc50s so we can hear the click track, and then eachother once a song begins, and if I dont use the effects loop I dont hear the tone my amp is giving me. Not a huge deal I guess but hard to get rocking when all I hear is a flat line of my bass. Also I was told that running a pedal between my bass and my amp instead of in the effects loop is not ideal. Why? Looking at a wt400 right now and apparently the effects loop is pre-tone controls, does this mean I can change volume of something thats been looped? But then I still have the lack of tone in my headphones thing. HELP! wow, this is a long post.
