i just got back from guitar center, where i played a fretless warwick corvette... WOW. i had never played a fretless plugged in before, because i figured the intonation would be hard and my brain associates "fretless" with "jaco" so it seemed out of my league. but it was SO much fun to play, and not very hard at all to intonate correctly, especially with the little dot markers on the side of the board. i found myself playing familiar lines and hardly making any mistakes at all. plus, now i can see why some people call frets "speed bumps," because my playing seemed so unhindered and lickety split... so now i'm jonesing bad for a fretless. how much would it cost to have a bass professionally defretted, and maybe a whole new fingerboard put on?
