The Tornado Stealth 80 is the Neodymium counterpart of the ceramic powered Electric Lightning. The Stealth 80 is extremely efficient, with slightly scooped mids, and it shines in the cleanest as well as in the heaviest tonal applications. It delivers exceptional punch and attack, retaining all the clarity needed for palm-muted riffs and power chords, as well as crystal clear clean rhythm playing.

Guitarist Description
Well balanced from low to high end with firm mids and sparkling highs. When presented with overdrive distortion, remains smooth with detailed note definition.

What a sound ! Tight, deep firm and bright with smooth overdrive really qualify this speaker. I was surprise how aggressive it is, but in a good way. It helps me to get through the mix with ease and it's highly controlable !! In clean channel of my Diezel,it stay detailed in the treble, deep in the bass and warm in the mids. You can play everything!


I ended up buying the Tornado Stealth 80 to go in my Bolt 30 watt tube combo.

Next to my Bolt 60 with the Tornado 100, these amps which otherwise sound identical, sound very different with these pictures. The Tornado Stealth 80 is very tight in the low end as advertised, and possibly a bit aggressive (I'm not big on metaphor when talking about sound), while the Tornado 100 is "rounder" and has more even-frequencies all around. Of course, the Tornado 80 is brand new and so I suspect it will take a few months to really hear what the speaker will end up sounding like, but for now I'm mostly satisfied.
