Carl Martin released the HeadRoom Mini Dual Channel Digital Spring Reverb, a compact digitally emulated take on its larger HeadRoom True Spring Tank Edition, news of the release appearing on March 25, 2025¹². The original HeadRoom units were released in 2011¹.

The pedal is built around two independent channels, each with its own Reverb, Tone and Decay controls, switched via a Select A/B footswitch alongside a Bypass/On footswitch³². It has mono and stereo inputs and outputs, buffered bypass, and a remote switch jack in a metal casing³. Guitar Pedal X describes the enclosure as a mid-size 1590BB style². Carl Martin's development account says the DSP was integrated into an analog circuit to capture the nonlinear behavior of a spring tank, with prototypes tested by musicians at the company's Grenaa, Denmark, studio and in recording studios worldwide¹.

The stereo I/O is the main change from the original, which was mono only¹. Guitar Pedal X reports the HeadRoom Mini costs $279, the same as the larger original².

Guitar Pedal X called the pedal "a smart enough device" while noting that many DSP spring-style reverbs already exist, and that some players might prefer a genuine spring tank². Pedal of the Day, which published the release, said it was "really loving the sounds coming out of this pedal"¹.
