Anyone ever taken a less expensive bass in their collection, removed the frets and played it as a fretless? Did you fill in the fret slots? Did you gloss up the fretboard (that I have seen in some conversions)? Was the existing fretboard even enough or did you have to sand/polish it to remove bumps? Ever done it to a short scale? I'm considering it, even though there are inexpensive fretless basses out there nowadays, which prompts a final question: anyone own either a Squier VM fretless or an Ibanez fretless. I am constantly astonished at the quality of these. Thanks.
