Been looking at this old bass on ebay, I was wondering if its just a grubby neck like it looks to be or is the fingerboard worn? (especially fret 4-8) And if its just dirt why didn't they clean it? Something for nearly £2k should be cleaned before sale..I would have hoped? http://www.ebay.co.uk/itm/Vintage-1991-Warwick-Thumb-Thru-Neck-Golden-Era-Left-Handed-Bass-Guitar-w-Case-/121599437060?pt=LH_DefaultDomain_3&hash=item1c4fe42904 Grubby? Worn?
