Jimmy Im lovin' the MJ w/ Roland A37 combo so far, now that I have 35+ gigs under my belt with it during the last month......
It does take some intense homework to get it just the way you want,re: learning its navagation, tweaking sounds, styles, etc, etc, but once your done its an awesome piece of gear that really does so much for the OMB player & beyond....I just got the FS6 pedal also which should make life easier on stage.....I'll look into the vocalizer down the road also.
I'm glad I bought it.

Take care

Don
