GaryDay has a very nice looking 66 jazz bass in black with matching headstock. Looks a good buy for £6k. Happily for me, I have 3 pre cbs jazzes, all pretty much original, other than the odd screw or missing cover. I always buy on approval subject to taking them to see Martin Petersen for a second opinion/check over. No genuine, confident seller would object to that. I am always open to the purchase of another pre 65 jazz and have never regretted a vintage purchase. If you are careful, nor will you.
