I've owned a pretty weak P-Bass for the past 6 years, and was thinking of getting a new one. What I was wondering was if it would be smart to de-fret my P-bass and upgrade the pickups when I finally got my new one, mainly so I'd have two basses to play on. SO is defretting ever a good idea? Will the sound be good if the bass wasn't designed as a fretless? spanks.
