NEW - The Supro Thunderbolt Plus amplifier adds switchable power amp topology to the legendary 1964 Supro Thunderbolt, giving you the original 35-Watt “Class A” Cathode bias sound as well as beefy 45-Watt and 60-Watt Grid bias modes for additional headroom and tonal variation. This unique design is implemented via a three-way selector switch on the front panel. 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 theatre stages, with overdrive completely controlled by the guitar’s volume knob.

The 35-Watt and 45-Watt modes both deliver the sag and bluster of the 5U4 tube rectifier while the 60-Watt mode uses a silicon rectifier to unleash maximum Thunderbolt power. The 60-Watt mode’s faster transient response and ample headroom is wonderful for pedals, and brings the Supro sound loud and clear to any size venue. 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. The variable power switching found in the Thunderbolt Plus model is an over-the-top hot-rod custom luxury guitar experience, decadently brought to you by Bruce Zinky and Dave Koltai.

In an effort to recreate the musical glory of the original Supro amplifiers, Supro Has partnered with Eminence to bring you a series of USA-made speakers unlike anything else available today. Using a recipe that includes an edge-wound voice coil, ceramic magnet and lightweight stiff paper cone, the custom speakers found in Supro amplifiers deliver vintage American (i.e. Jensen) tone, with far more power handling, superior efficiency and nice firm bottom.
