Price is irrelevant, although I know it can make a big difference. I havent had too much fretless experiance. Only really some mediocare Fenders/Deans. Played some Old Ernie Balls that my teacher has, and I beleive I also tried out a Roscoe Fretless. But my favorite so far, goes, surprisingly to. The 4 String Warwick Corvette Standard. The BEST sounding fretless, and best playing I have ever layed hands on. What are your personal favorites?
