I recently bought a fretless bass that has NO mwah sound (not my favorite word but best way to describe it). It's a 2008 mim jazz bass with rosewood fingerboard, roundwound strings, nice straight neck and low action but it sounds exactly like a fretted jazz. I like the sound of a jazz bass but I already own a fretted jazz and bought this because I was looking for the sound of a fretless jazz bass.
This is the fifth fretless bass I've owned and all the previous ones had the sound one would expect from a fretless. I'm more perplexed than bothered by it, I'd really like to figure out what's different about this one. Any ideas?
