Thanks Luke, sign of the times I guess mate. I keep going around in circles on it to be honest, one minute I think I should never have bought such as expensive bass given that I already had a fretless Jazz (and one better suited to me because it has a fat neck whilst the '68 has a very thin neck), the next minute I can't believe my luck to own such a dream instrument. The more I play it the more I want to keep it, so I'm keeping it firmly locked in its case at the moment.
I'm going to list it on eBay this evening, so to avoid the stress of that I'd welcome cash offers in the meantime
