The Supro Thunderbolt is a vintage-style tube amplifier that offers classic tones and rich harmonics, making it a favorite among blues and rock guitarists.

The Supro Thunderbolt S6420+ typically features a Class-A, all-tube design with a single Supro TB15 15-inch speaker, delivering 60 watts of pure vintage power. The amp is known for its warm, smooth overdrive and touch-sensitive dynamics, making it an excellent choice for players seeking that classic bluesy tone.

With a straightforward control layout consisting of volume, tone, and a tube-driven spring reverb, the Thunderbolt offers a user-friendly experience and allows players to dial in their preferred tones with ease.

Despite being pre-owned, this amplifier has been well taken care of and is in good overall condition. It has been tested to ensure that all functions and controls are working correctly, providing the signature Thunderbolt sound. There is some small signs of wear, which is common with used amplifiers, but this should not affect the amp's performance or sound quality. Additionally, the leather handle may have a split in the middle due to regular use, but it should still be functional and easy to carry.

Whether you're a vintage gear enthusiast, a blues aficionado, or simply looking for a reliable and iconic amplifier, this used Supro Thunderbolt S6420+ provides a great opportunity to add that classic tube-driven sound to your arsenal.


This amp is in good condition, with small signs of wear and a split leather handle.
