1976 Fender
Super Twin
“Do you feel that the old Fender amps are better than the newer Fenders?
They seem to warm up sooner. They wouldn’t have the wide tonal range that the new Fenders have —particularly the new Fender Super Twin which has a graphic equalizer, a master volume control, overdrive, and all that—but I probably have some interest in old amps over and above the actual music because of their appearance and because the guys in the Fifties used them” March 1978 http://www.roryon.com/GP78.html
