huh, I never heard of a jukebox musical (a musical of recent hit covers). I think it depends on what synth sound is needed and if a pedal can do it. You will be playing a lot of melody parts in the bass. I've sold off most synth pedals except EH bass micro and B9 (organ emulation) and I haven't tried the new MXR, but most of them have too much latency (delay before sound happens) for me. The micro does cop a good Funkadelic/Bootsy sound (it's basically analogish octave, squarewave and very controllable down or up envelope) but doesn't handle a B string well. But it aint pfat like a moog or other monophonic keyboard.
