A hot-rodded version of the reissued Thunderbolt, the Supro S6420+ Thunderbolt Plus tube guitar amplifier features a three-way rectifier switch option for more headroom and versatility. 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 the Thunderbolt Plus, you'll be treated to a huge, raw, overdriven, rock 'n' roll tone cascading from a custom designed 15" Supro TB15 speaker. Make no mistake, the Supro S6420+ Thunderbolt Plus tube guitar amplifier produces pure rock 'n' roll power.
