Hello all, 
                    In setting up a jam man for live rig, w/mixer,  what
would be the best way to put it in chain, so i can catch all instruments in
loop? as an aux send, or on the main outs? Forgive this "newbie" question,
but would appreciate any tips or examples of setups.- Thanks! - Brendan
