Overview

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.

    Comments about Supro S6420+ Thunderbolt Plus 35W 1x15 Tube Guitar Combo Amp:

    No reviews needed, I have a few amps cost more than this and a lot bigger stack but this one blows them all away. Go play it gently and the guitar behaves like it is suppose to but go hard and it will Rock on with you as is cranked up. No need to step on any gadgets or move volume settings. It plays soft when you do and rock out when you do.

      Comments about Supro S6420+ Thunderbolt Plus 35W 1x15 Tube Guitar Combo Amp:

      Some of the professional reviews, and brand specific promo, detail the original version and harp on who supposedly played the amp. Who cares. They also say that the original was only great with tone and volume cranked to ten. I don't know about the original, but I walked into a store and played through many amps and this was the clear winner. Two knobs and the truth is very accurate. Tone at about 5-10 is optimal, volume 2-8. Takes pedals very well and can growl on its own. My G&Ls are sparkly, the gibson drives it to more crunch and the tone helps mellow the Parker Fly Deluxe gen 1 which is often criticized as being too bright (favorite btw). Wonderfully simple tube amp.
