Just came in the other day. A friend was out scouting yard sales and came up with this jem. It's either a 66 or 67 twin reverb. I would say 65 but it has Fender Musical on it instead of Fender Electric . This changed sometime in 65/66. It needs some TLC but I gave it a quick check, mounted a temp pair of 12's in it for a test and it works. Boy does it work. Incredibly loud these things, reverb and vibrato still work. Will take a couple pics when i get a chance but I am on the hunt for a good pair of 12's for this amp...
