I'm not sure if I should get one of the loop boxes (custom A/B/Y type) or go with a mixer. here's what I want to do:

I have a boomerang looper pedal. I have some guitar pedal effects that will be before the 'rang in an effects loop. I want to loop an acoustic guitar and 2 vocal mics.

I have an (A) acoustic guitar (taylor with a lr baggs M1, 1/4" instrument) , (B) Shure green bullet vocal mic (1/4" instrument) and a (C) shure beta 58 vocal mic (I can get an impedance adapter or use a preamp if needed).

I'd like individual inputs for A, B & C. One effects loop that can be used with A, B, & C; together or independent. Individual outputs for A, B & C. I want the A, B & C outputs to always be on, whether the effects loop is on or off for that input. i.e, the only selecting is whether the effects loop is on for inputs A, B and/or C. otherwise it's a bypass box.

this is for live performance to either a small mixer to powered speakers or a 3ch acoustic/vocal amp....DI for each channel to the FOH board, so without another mixer I'm not sure how to obtain the ease of selection a switcher pedal would give me.

any advice is appreciated, right now I can perform with the effects on all three inputs at once thru an effects loop of an acoustic amp...but to turn the effects loop on and off for each input would be great.

I've also hooked everything up to a mixer and can control the effects loop thru the aux sends, but this is by hand and defeats my purpose (on the fly changes with a foot controller).

thanks, Chris
