I just joined my first band, with a female singer/songwriter/guitarist. I played my first gig with the band on new years, and she recently asked me if I would do pre-production with her and record some bass tracks. I said I would do it, but I haven't yet asked about if im going to be making any money. I assume I should be making some percentage per album sale. I guess it would be a good idea to ask about it. Im not really sure how this stuff works...anyone have any knowlege advice they could share?
