Check out Mikey Guitars by clicking on the link below and be amazed with what you see! http://mikeyguitar.com/bass.asp The world's first fretted / fretless convertable bass. 34" scale to boot. Check out the photos of the 2 modes. With the flick of a switch you can be either playing the bass fretted or fretless. Price tag $6,000.00 US or $7,000.00 Canadian. There's one that just arrived at a local guitar shop. I'm trying to make it there to check it out, just out of curiosity. TD PS - He also has a guitar version. Cool.
