Who we are...


Hello, my name is Stephen Finkbiner, owner of Finkbiner Industries LLC and designer/engineer/builder/HMFIC of HAVOC amplifiers. I am a professional engineer registered in Missouri that loves tube guitar amplifiers and awesome guitar tone. I built my first guitar amplifier, a headphone amp, in 2004 when my dorm neighbor complained about the volume of my Fender Deluxe 90. From there I was hooked and on the quest for the ultimate guitar tone.

In 2021, I decided it was time to go pro and share my designs with fellow guitarists. There are surely tube amplifiers already out there, but not many separates, not many rackmountable, and even fewer are hand built and wired. Try mine out, I think you’ll like what they do for your sound and look.

What we're about


 
Tone. First and foremost. It’s gotta scream “play me”.

Simplicity. HAVOC amplifiers are single channel and laid out for low noise. You’ll be shocked how quiet a high gain beast like the Hot HAVOC can be when designed for circuit simplicity.

Flexibility. That’s why HAVOC amplifiers are rackmountable and separates.
