At the risk of dating myself, a silverface fender isn't what you're after if you are chasing classic, or even hot, tone. Most of the silverface stuff was post CBS and while they introduced cost cutting measures and design changes to the fender line, these changes were intended to make the amps cleaner and more consistent. Good idea from a manufacturing standpoint, but the tones that many people deify are coming from the era when the amps were built with whatever was available, basically. So what you have is either sorta bland sameness or hit or miss on the older pre CBS stuff. That being said, I have witnessed, in a vintage gear shop, purchases made of pre and post CBS fenders and other "old" amps that sounded to my ears like big heaping steaming piles 'o' crap, knowing full well that the people that bought them were succumbing to the mystique of "if its old and tubes, it must be good". To that should be added "I don't really care if the speaker needs re-coning and the transformer is rusty and moldy and it needs all new caps and it smells like cat pee... its Vintage!" My grandma's butt is vintage, but that don't make it smell better. Anyway, Ive heard good players get some pretty good stuff out of their PODs. In a few years, the technology will be even better and probably cheaper taboot. Also tube manufacturing technology is kinda primitive so not so environmentally friendly. We could mine the new-old-stock vein for years if it weren't for those damned audiophiles who claim they can hear "improved imaging and soundstaging from their kimber cables and special cd cleaner fluid" Double-blind embarass-the-audiophile listening tests anyone?
...Sorry, that last bit is one of my favorite rants...damn tube hoarders!
All respects.
