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. Available
once again in all its bonafide Supro glory, the Thunderbolt returns in
style.
