I've been playing bass for a while, and have done some studio work, but mostly just for my bands and for friends. I've never just been offered a studio gig (especially without advertising myself). Today I got an offer to record backing tracks for some classic rock covers. The guy is going to be using these lines live and wants a "real" bass player to record them. I think it's a great idea, especially because I don't have time to play with him live even if he asked. I've been searching the forums for a suggested pay I should ask for something like this, but the closest thing I found was this thread. That was 6 years ago. lol. He wants to record 5 tracks at a time doing a few different sessions. I asked for the songs ahead of time. They're fairly simple tunes and I'll be able to learn them easily given some time to practice them. I'm thinking about asking for $40-50 a song, but I'm not entirely sure. Any suggestions?
