Background

I’m Heiko Frost, a designer and engineer with a lifelong obsession with sound, structure, and how things behave under pressure. My background spans product design, systems thinking, and years of working at the intersection of craft and precision. I came to amplifier building not as a nostalgia exercise, but as a technical problem worth solving properly.

The Path to Amplifier Design

My journey into tube amplifiers began with dissatisfaction. Too many modern amps chase features at the expense of clarity, or lean on distortion as a shortcut for character. I wanted clean power that stays articulate as it is pushed, circuits that remain stable under real playing conditions, and designs that reward touch rather than mask it. What started as late-night prototyping and teardown work slowly became a focused practice of listening, measuring, revising, and starting over.

Frostechnik

Frostechnik exists to build guitar amplifiers as instruments. Each design is engineered deliberately, from power supply behavior to mechanical layout, with the same seriousness applied to any professional tool. These amps are not meant to impress on a spec sheet or shout from across the room. They are built for players who care about feel, headroom, and honesty, and who understand that the best tone is often the least obvious one.

Design Philosophy

My design philosophy is simple. Remove what does not serve the signal, and refine what remains until it is dependable and expressive. Every circuit choice is intentional, every component value earned through iteration rather than convention. I favor stability over cleverness, balance over excess, and designs that reveal the player rather than impose themselves. An amplifier should not fight you, flatter you, or hide your mistakes. It should tell the truth.
