Supro S6420+ 1x15 Supercharged Thunderbolt PlusThe 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

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.

It's just perfect!!!
Color: Black, Color: Black
I looked at all of the different watch box cases and I am so glad that I chose this one! It is well made and looks more expensive than it was. I love that I can see everything at once instead of having to open drawers to only glimpse at some of my stash. I bought this for my 20 watches and even though I can't fit my small wrist watches on the pillow because this is made for a man's watch, it really doesn't bother me. It's easier to take out a watch or put it back. It really freed up a ton of space in my jewelry cabinet for my jewelry! Love it!!!

Good case
Color: Black
Great watch case. Fits all my 43mm-48mm watches. Any bigger they will run against each other. But altogether a solid purchase.
