So I played a blackface era pro reverb today at my local GC (don't know exact year) but imo, it was the sound I've been looking for in my head and think that is the next amp for me. BUT, I have found two really clean vintage examples, a 1966 blackface pro reverb (at 1500) and a Silverface drip edge pro reverb (at 1000). Now my intuition says get the Silverface because as far as I know, the drip edge ones are the same circuit as the blackface ones. Also, 500 dollars is a big difference, especially when the majority of that difference is spent on collectability. But since blackface amps tend to go past the 2k mark these days, do ya'll think it's a good idea to pay the extra money for it? Also, am I right in saying that the 68's are pretty much the same circuit? If not, what differences should I expect if I go that route. Again, the blackface pro that I played today blew me away so I want to find one that sounds rlly close to it (obviously every vintage amp will sound slightly different, but you know what I'm saying).
