PRODUCT DETAILS
Supro Thunderbolt S6420+ Reissue in Excellent Condition!
Up for sale is a Supro Thunderbolt S6420+ Reissue, a faithful modern recreation of one of Supro’s most legendary and sought-after amplifiers. Known for its thick low end, raw midrange punch, and unmistakable vintage character, the Thunderbolt has long been a favourite for players chasing bold, harmonically rich valve tones with serious attitude.
This example is in Excellent condition, showing only very light signs of careful use. The tolex, grille, and control panel are all in great shape, and the amp functions perfectly. It has clearly been well looked after and sounds absolutely fantastic.
The Thunderbolt S6420+ delivers huge, authoritative tone, with warm, round cleans that quickly give way to thick, organic overdrive as the volume is pushed. It excels at blues, rock, and roots styles, offering a raw, dynamic response that feels incredibly alive under the fingers. The amp’s simple control layout encourages you to work with your guitar’s volume and picking dynamics, rewarding expressive playing.
Despite its vintage-inspired design, this reissue benefits from modern reliability and consistency, making it far more practical than an original vintage example while retaining the iconic Supro sound. It takes pedals well and pairs beautifully with both single-coils and humbuckers.
As is standard practice with any new arrival in store, this very cool Thunderbolt has been through the trusted hands of our team in our onsite workshop to ensure it is in tip-top shape for its new home and owner!
