2015 Supro Thunderbolt s6420, in excellent condition with almost zero signs of use. Sounds huge.
"Just in time for its 50th anniversary, Supro has reissued the S6420 Thunderbolt tube guitar amplifier. Like the Fender Bassman, the Thunderbolt was originally intended to be a bass amplifier. While far from a stellar bass amp, the Thunderbolt quickly became a holy grail tone device for electric guitar players. Indeed, the first time you crank up this Thunderbolt reissue, you'll be treated to a huge, raw, overdriven, rock 'n' roll tone cascading from a custom designed 15" Supro TB15 speaker. Simplistic, sporting only a tone and volume control, the Supro S6420 Thunderbolt tube guitar amplifier's cathode-biased 6L6 output section produces 35 watts of pure rock 'n' roll power. Call your Sweetwater Sales Engineer and get plugged in!"
