I remember the first time I saw one of these fitted to a bass - brilliant piece of design - why these weren't introduced years ago I'll never know.

I have a neck thru fretted 5er - really nice bass to play - both on and off the strap. Nicely balanced and really playable neck.
I'd offer a trade of sorts but I can see that you're after a sale ideally.
Good luck with the sale. Congrats to the buyer!!
