I have about a dozen or so basses. Some I don't play much - and two or three I play a lot. I would like to thin the herd, but I think I'd miss even the ones that hardly get played. Most are hanging on the wall, so in a way serve as artwork.
When I took my unlined fretless bitzer precision to a jam night a week or so ago - the first time I've played it for a long time, it really felt like having a new bass as it was so unfamiliar. It seems there's something about playing an unlined fretless that makes people think you must know what you're doing as I got lots of complements about my sound and playing - which wasn't far off how I normally sound or play when people don't normally give a flying monkeys
