The 1966 Supro S6420 Thunderbolt is a classic, vintage 35-watt tube amplifier that delivers a unique, gritty tone beloved by players who crave a raw, retro sound with character. Known for its distinctive voice, the Thunderbolt combines creamy cleans with a punchy overdrive that can break up beautifully when pushed, making it ideal for blues, rock, and other vintage-inspired genres.
 
This particular model is all original, including its original Jensen 15" speaker, which contributes to its rich, full sound with a deep low-end response and detailed mids that really shine through.
 
The amp has been carefully serviced to ensure it performs reliably while maintaining its vintage authenticity. The transformer has been replaced to keep the Thunderbolt in top working condition, and resistors were added to the power transformer center top. The pots, sockets, and jacks have all been cleaned, ensuring smooth operation and crackle-free performance. Additionally, the AC cable has been replaced for safety and durability, making this amp a solid choice for today’s musicians who appreciate vintage gear with the assurance of reliability.
 
With its original components and a few thoughtful updates, the 1966 Supro S6420 Thunderbolt offers the kind of classic tone and reliability that collectors and gigging musicians alike can appreciate, all while retaining the nostalgic charm of one of the most iconic amps of the 1960s. This amp has been serviced by our technician, and is ready for the stage/studio!
