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.


  • 35-watt cathode-biased 6L6 output section delivers plenty of tone and volume
  • 1 x 15" custom designed Supro TB15 speaker delivers classic vintage sound
  • Tone and volume knobs makes dialing in your tone simple
