The Supro S6420 Thunderbolt grants players a simple way to precisely shape warm, vintage tones and are available at surprisingly musician-friendly prices. Continuing in the tradition of their new amp line, Supro has made the Thunderbolt based off the design of its vintage predecessor, the '64 Thunderbolt in this case. The Thunderbolt reissues deliver the same full range of sound and cutting mid-range, pulling out the personality and character of whatever guitar you plug in. For versatility in one sleek all-tube combo amp, check out the Supro Thunderbolt.
