The Supro S6420+ Thunderbolt Plus is a modern reimagination of a classic, delivering both historic charm and contemporary versatility. Supro's legacy dates back to the 1930s, with their amps gaining iconic status among musicians like Jimi Hendrix and Jimmy Page. The original Thunderbolt was renowned for its raw, overdriven sound, a result of its underwhelming performance as a bass amp. Its unique tone quickly captivated guitarists and became legendary.
 
The S6420+ builds on this heritage, offering a refined version of the Thunderbolt's distinctive sound with added functionality. It features a 35-watt cathode-biased 6L6 output section, providing ample volume and tonal richness. The 1 x 15" custom Supro TB15 speaker is designed to deliver the classic vintage sound that has made Supro amps so desirable.
 
One of the standout features of the S6420+ is its 3-way rectifier switch, which expands the amp's versatility. This switch allows you to select between:
35-watt cathode-biased 5U4 tube rectifier for a warm, vintage feel.
45-watt grid-biased 5U4 tube rectifier for increased headroom and dynamic range.
60-watt solid-state rectifier for a modern, high-power option that enhances versatility.
 
With straightforward tone and volume controls, the S6420+ makes it easy to dial in your perfect sound. Whether you're seeking the classic, gritty overdrive of its predecessor or need the headroom for a modern gig, the Supro S6420+ Thunderbolt Plus is designed to be a versatile and powerful addition to any guitarist's setup.
