Welcome
HAVOC guitar amplifiers are custom hand-built, hand-wired, vacuum tube amplifiers brought to you by Finkbiner Industries LLC. There are no opamps or digital circuitry to be found in the signal chain. HAVOC circuits are designed for simplicity and laid out for low noise; no bells, whistles, gadgets or gimmicks that you will never use. When you plug into a HAVOC amplifier, you know you are getting pure unadulterated valve tone.
Model Lineup
We currently have three models available:
 | Mild HAVOC Preamplifier: A mostly clean tube preamplifier, powered by two 12AX7’s. Shimmering clean tones to bluesy breakup. |
 | Hot HAVOC Preamplifier: A distortion machine of a preamplifier, powered by three 12AX7’s. Not for the timid or feint of heart at higher GAIN settings, but it still rocks a nice clean sound as well. |
 | Studio HAVOC Power Amplifier: A beauty of a 10 watt push-pull power amplifier, powered by one 12AY7 and two EL84s. Perfect for practicing at home or recording in the studio. Easily driven by a HAVOC preamplifier. |
Stay tuned as we release new models in the future (I’m looking at you, Medium HAVOC….)
For rackmount or desktop use
