Saw a blues band last night. I'm friends with the singer. Anyway, the bassist was using a Galveston 8-string bass, tuned F#-B-E-A-D-G-C-F. He played it well, and even doubled on keyboards. He claimed that bass had the range of a grand piano. If true, that's impressive enough. My friend the singer asked me to sit in, using the 8-string. I declined. The string spacing looked pretty tight. A train wreck waiting to happen if I tried to play it. Wishing it were 8 string in pairs, or just a plain old four. It was a nice bass, but if I go for an ERB in the future, it'll be a five. I just don't see the need for more than that. Edit: After doing the math, it had a range of 61 notes, being a 26 fret bass. Not quite grand piano range, but a lot of range nonetheless.
