I've noticed that whenever someone mentions that they are considering buying a new reissue amp (usually a Fender) immediately there is a feeding frenzy of posters telling them to buy vintage and quoting prices that are usually lower than the cost of the reissue new. I wonder just how much these folks really know about buying and trading amps. The classic vintage amps made between 1949-1967 are probably the most sought after, followed closely by the Silverface line from 1968-1980 roughly. A Super Reverb made in 1975 would be 41 years old if I bought it today, a blackface amp would be ~51 years old today. My point is that it is very rare any more to find a amp that old that has not been modded by someone (often with little or no skill), had master volumes added, speakers changed, transformers changed, etc. And many need to have the power sections rebuilt due to leaky caps. I have owned many amps in my lifetime and when you buy a vintage amp you have to factor in the cost of getting it up to what I call "gig worthy" level and good amp techs are not cheap. If you can actually do the work yourself then you are way ahead of the game and I envy you. I am fortunate enough to own a mint condition 1966 Tremolux & cab, but I also own a Super Reverb Reissue that I play out with that is excellent, so debating vintage vs new seems pointless to me, even many of the vintage amps I've owned in the past have all sounded different from each other!
