Ah, yeah, that is a bit cramped. But like Jimmy says, probably nothing to worry about. I think once it's tuned to pitch, strings stretched, then tuned back to pitch, it should be solid. I've had three 8 strings (currently a Rickenbacker), and a Hamer 12 string over the years. Total riff machines! It's hard to pick one up and NOT come up with a new song idea. And FWIW, I play multi-course basses exclusively with a pick.
