My friend just brought down a '74 jazz bass from his home and is letting me borrow it for a few days to see if I want to buy it. The finish has cracks in it, but it's a natural finish so you can't tell unless you're up close. The tuners are really stiff and a bizatch to work with. The neck pocket looks like there's a shim on either side to help fill in the gap. The bridge pickup route is too big for the pickup. But man does she play. I put a set of DR stainlesses on it and it was instant Marcus. Question is, should I go for it? Is there anything I should be really worried about? And what's a good price for this bass? The owner is my friend so neither of us wants to rip the other guy off.
