I learned to play bass by sitting with my mom's old Peavey T-20 FL in my room and playing out of an Essential Elements beginner book. I look back at the experience fondly, but I've decided that it's time to move on to bigger and better things. I'm looking to sell the bass, but I honestly have no reference points as far as price is concerned. I saw this on a website about old guitars and basses: "as well as what would turn out to be a fairly-rare T-20FL fretless version." Does this mean that it's more valuable than other T-20's nowadays? My bass's parts and electronics are all original and work very well, and I have the original case with it. Could anybody shed some insight on this?
