I'm going to be getting another bass soon and was thinking about de-fretting my current bass (RBX170). I'm not sure if it would sound good fretless though, and if I should leave it fretted as a backup bass. The frets are also pretty worn down, but hasn't affected the sound at all. I would like a fretless bass, but I just don't have the money to get one since I'm going to get a Ibanez ATK300 for my next bass. So fretless Yamaha RBX170 good idea or bad idea?
