I wonder if it could be converted into a fretted 5. It's really lovely but a fretless 8 string seems like a narrow niche.
Yes, indeed, it certainly is a narrow niche. No doubt about it. I think the only bass that has an even narrower niche is the John Judge double neck.
I have been having a blast playing it and trying to improve as a fretless player. Admittedly, I am not that good at fretless.
A big part of the challenge for me is that I have short scale basses, medium scale, long scale, and an xl scale (36'').
If I were to really want to get good at fretless, I'd just need to stick to one scale length and instrument for quite some time.
I am a big fan of fret markers.
The Series II fretless 5 that I used to have was pretty easy for me to play because of the fret markers. I understand that some people don't like the way they look but they certainly are helpful!
