I messaged seller to find out history..
They replied that the bass was part of a 'famous bassplayers' personal collection, and had simply been stored unused from new.
Amazing IMO, I have an '85 Walnut finish one of these, and it was my mainstay for years, best feeling bass I've owned, and an unbelievable action, its like putting on an old pair of trainers. But condition after years of gigging is not quite the same as this..
Its the colour of this too, never seen that transparent finish before.. 😯
