I'm starting to get calls for studio work (upright, fretless, fretted). I just got my first call from an actual professional and he's asking me my rate. I don't know my rate I'm not an unbelievable musician, but I'm passable, and responsible, which is all a lot of people want, I gather! He's recording 12 songs in 4-song sets. Anticipates 4hrs rehersal time, plus 4hrs studio time per set. Any idea of what I should ask? Don't want to go too high or too low. $160/set sound fair?
