I am a bass player. I am auditioning for a few obscure-sounding bands and want to take along a new dimension to my instrument. I have been looking at Guitar Rig + the guitar rig pedal. Looks great. Just wondering whateveryone thinks about using my macbook as a session/live means of using these effects (as opposed to just using it for studio/recording)? i have the 2.53/4gb mac. Can I rely on my macbook to do all this without having a meltdown on me during the middle of a gig? I also have Live 8, but guitar rig looks a lot more user friendly in terms of using it as a live/session instrument for bass. I have visions of my macbook sitting on top of my bass amp, bass wired through pedal > macbook/guitar rig pro > back out into my bass amp. Will this work? Or do I need something else before I wire my mac into the amp? I have a small behringer 4 channel mixer too, if that helps.
