I just bought this chassis from a well known and somewhat infamous vendor... after close scrutiny, I actually believe it to be a genuine 65-66 JTM45 tremolo chassis. The tooling marks and layout, transformer mounting holes etc all line up where they should be. It's impossible to verify of course, but in the end it doesn't matter too much. It's never going to be a collector's item anyway, and the price wasn't too bad. I would appreciate some input from the vintage experts here on how to proceed. I am planning to do an accurate repro of the infamous Clapton Bluesbreaker (I'm not the first one to attempt this of course). I have lots of vintage parts, but missing a few important ones like the impedance and voltage selectors, as well as board material. And transformers of course. I was planning to go with Merren as usual. The most pressing concern is front and rear panels. I bought some repro panels along with it that were supposed to match, but they are not correct. The rear panel is just wrong altogether, and the front panel, while close in appearance, has the input holes in the wrong place. I suspect the front panels were modeled after a JMP steel era chassis, but all the genuine JTM45 tremolo chassis I've seen has the input jacks very close to the last volume control. Any tips on where I can have some really accurate panels made?
