The Supro S6420+ Thunderbolt Plus is a true powerhouse of a valve combo. A 15" speaker and switchable poweramp section allows you to go from a 35 watt “Class A” Cathode bias sound to beefy 45-Watt and 60-Watt Grid bias modes for additional headroom and tonal variation via a three-way selector switch. The only other controls are Volume and Tone; it doesn't get much simpler than this! True boutique tones are on offer as soon as you plug in. Pop in to our Glasgow shop Merchant City Music for a demo of one for yourself. If buying online we ship fast across the UK and Europe.

Supro S6420+ Thunderbolt Plus - 60/45/35-watt 1x15" Valve Combo

The Supro S6420 Thunderbolt Plus dishes up truly authentic vintage tones with all of the character, harmonic richness and sweet midrange of legendary amps that helped define the sound of modern rock and roll.

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!
