So, I bought one of these recently, cost about £270 plus postage but I see they regularly go for anything up to like £500-600, which is MENTAL!
It IS a thing of beauty... BUT.... All the money is really in the 'signature' which isn't actually there 😂 and the unique style of it- the Tele headstock, the old pickguard config and the split pickup etc. But if I'm being honest, it's a bit cheap feeling and sounding... Don't get me wrong, the neck feels great! It's really nice to play. But the body is quite lightweight (a bonus to some!) but the pickups sound pretty thin, and they actually somehow look a bit cheap and nasty too. I think I just feel like it's a cheaply made bass with a pretty big price-tag just cos of the Mike Dirnt association.
In saying all of that, I'm treating it like a project bass... it's getting a paint job, a new bridge, new pickups, new pots, and I'm treating the light weight as a bonus for those longer gigs! But I think if you had £400 to £600 kicking about, I'd figure something else out.
