I'm getting back into bass after 6 years out due to school and travel. Previously I played symphonic, jazz, swing, and bluegrass, and folk My local shop has a some nice 7/8 for rent ( I'm 6'7" tall) They also have a couple of c extension 7/8 for rent. I will be playing mostly solo for the next year or two, would a c extension be worth it? Tune in fiths and play some cello pieces? For my own enjoyment, or just stick with standard tunning?
