I just got my second fretless, a Brice 6 string. It's nice, sounds and looks pretty good. It's not great quality, but it's good enough for now. It's nowhere near the quality of my Dean Edge 5 fretless, also made in Korea. Anyways, I'm having trouble intonating. If I'm not looking, I'm always flat, and I hit the end of the neck looking for Bb and F. Should I be concerned here? The 35" Dean was my first ever fretless and I'm just getting comfortable intonating that. Basically I want to hear from your fretless players, if I work at this, is there hope that I can get used to the multiple scale lenghts on different basses? Or should I just sell one of these, admit my mistake, and get matching ones. How do you deal with it? BTW both of these basses are unlined.
