Never tried an L2000 or any of the similar humbucker type models (I’m a bit unsure about the model numbers and types) but all I know is that after trying and having different P basses, nothing can touch this early SB1 - I don’t know how much they were new but like said above it’s fantastic build quality, the three bolt neck is great and the electronics and hardware really make it a sensible upgrade over the Fender Precision which is what I suppose it was intended to be. It’s basically the same but just a little more refined and it feels lovely.
I do agree that the new headstock shame is a little jarring and I think it’s right that they are quite rare basses considering - even in the US they aren’t that common but sought out by those ‘in the know’, so there are some bargains for sure. The best type of bargain - because you’re not paying for hype!
