One the Rarest amps ever, a true piece of American music history right here. For sale is a ultra rare 1966-67 Carvin 4-10n combo amplifier, a 4x10 SOLID STATE amp! Yes! in a era of tube amps Carvin was ahead of the pack when it came to new technology and had a solid state combo amp ready to perform on stage before anyone else. I have not ever seen another one of these for sale and not even one that looks close to it, the only other to have ever existed on the internet is on a catalog photograph located on the Carvin Museum website. This amp in particular sounds absolutely amazing to say the least. Everything here works as it should as it is fresh from the repair man, it is ready to rock and roll!
