I played a fretless J Bass the other day at Guitar Center and fell in love. IMO, much more enjoyable to play and sounds very clean. I slide a lot and the sliding on a fretless is amazing. So, im thinking about defretting my current bass, an Ibanez GSR200. Also, im in a band in the works planning to play progressive metal, how would a fretless handle playing metal? Can't think of a metal bassist that uses a fretless. any advice would be great, thanks in advance.
