The Carl Martin HeadRoom Mini features a compact, pedalboard-friendly design that recreates the depth and warmth of classic spring-style reverb using a digital engine. It is built with two independent reverb channels, each equipped with its own Tone, Reverb Level, and Decay controls to allow instant switching between two distinct sounds. The Decay control provides a wide range of adjustment, moving from tight, reflective spaces to long, ambient reverb tails. Designed for seamless integration, the pedal includes a buffered output to preserve signal integrity, a remote input for external channel switching, and full support for both mono and stereo operation.

When Carl Martin developed HeadRoom Mini, their goal was to capture the character and flexibility of the original HeadRoom — but in a more compact, pedalboard-friendly format. Instead of real springs, Carl chose a digital reverb engine that allowed them to recreate the depth, warmth, and movement of spring-style reverb while keeping size, weight, and power requirements practical.

Carl built HeadRoom Mini around two identical reverb channels, each with its own Tone, Reverb Level, and Decay controls. This lets us set up two completely different reverb characters and switch between them instantly. One channel can handle a short, bright room sound, while the other delivers a longer, darker, more expansive reverb — all without touching the knobs mid-song.

The decay control adds another layer of control, allowing us to move from tight, reflective spaces to long, ambient tails that feel far larger than the pedal itself. Used subtly, it adds depth and dimension. Pushed further, it opens up wide, atmospheric textures that still remain controlled and musical.

HeadRoom Mini is designed to integrate easily into modern rigs. The buffered output preserves signal integrity, especially in pedalboards with longer cable runs, and the remote input allows external switching between preset A and B if needed. Despite its compact enclosure, the pedal supports mono or stereo signal paths, making it equally useful on traditional amps and more complex setups.

Simple to operate, flexible in use, and built with the same design philosophy as the original, HeadRoom Mini delivers two instantly accessible reverb sounds in a format that fits naturally on today’s pedalboards.
