So last Thursday I had a guy come to the studio and he had a mid 70s silver face Princeton reverb. You know I have owned and still do own lots of classic amps but never a Princeton Reverb. I always thought they were just a tad too small for me and that my black face Deluxe could do anything the Princeton could do just louder and better. After hearing his amp I now know I was W R O N G !!!! to ever think that. That little amp just floored me. So now I'm searching for one - got to have one. The prices these days are really high and I don't want a reissue because I'd like to try some of the mods that are available. I've been considering building one so I'm asking has anyone here built any of the kits available out there such as Marsh & Mojo tone? I'm looking to get opinions since hand wired is preferred. Lots of people say that the black face ones made from 64 - 67 are the best but I've got to tell you that mid 70s silver face sounded awesome - I can't imagine any black face could sound any better. I also read that the Princeton Reverb amps from 1964 - 1977 were pretty much the same amp with very little changes made until 1978 when they added those stupid push - pull switches. True?
