OK, older thread but lots has happened since I started this!
Coincidentally, I picked up a 1464 about a month ago for giggles and I had my amp tech go through it. Just plugged it in tonight, through a Tube Screamer, and WOW, it sounds great!! It is sort of going to be a live amp for my guitarist since with repairs, I got it for under $400, and it's now practically brand new for a 50 year old amp.

Secondly, a few months after I posted this thread, I ended up getting a 1484 with jensen-filled cabinet and footswitch. It goes without saying that this thing is the pride of my recording studio. I have recorded at least 2 albums with it already, including one for me, and I will be buried with it. Here it is:

Finally, you'll see I've gone a bit SILVERTONE CRAZY, and I picked up a 1478 Guitar as well, all original with the "tin-foil" pickups. In GREAT shape, and it sounds fantastic. Plays well too after I had an expert set it up. In fact, I am going to use her onstage. Here she is with my 1484:

See what obsession can do?
