S6420 Thunderbolt—Two knobs and the TRUTH! The legendary 1964 “Blue Rhino Hide” Supro Thunderbolt is back. Renowned for its bold, full-range sound and up-front, honest midrange, the Thunderbolt covers a remarkable spectrum of vintage tone while wringing every ounce of personality from whatever guitar is plugged in. From clean jazz to Tele twang, soapbar blues to humbucker grind, the Thunderbolt dishes out 35 Watts of “Class A” tube tone from its vintage Supro dual 6L6 power plant. True to the ‘64 version of the Thunderbolt, a 5U4 rectifier tube is employed to deliver that unmistakable high-powered vintage sag. Normal and Extra-hot input options, combined with a wide range of available gain on tap, allow you to fine-tune the texture and response of this amp’s massive sound.
Turned all the way up, the Thunderbolt exhibits nearly zero self-noise; yet it puts out enough volume to be easily heard on large venue and theater stages, with overdrive completely controlled by the guitar’s volume knob. Massive custom transformers and lightweight, vintage-correct cabinetry—combined with the best-sounding 15” guitar speaker money can buy—put the Thunderbolt in a class of its own. With the amp turned all the way up, chords ring with exceptional clarity and definition, amidst copious amounts of tube overdrive and output-stage saturation.
