About

Tune your pedalboard. No compromise. When you are on stage, you are not holding your phone up to squint at a small needle. SUS4 Pedal Tuner gives you a giant-display chromatic readout designed to be read at floor level, from a few feet away, under any lighting condition. It is the phone-based version of the floor tuner on your pedalboard — minus the extra cable. Presets remember your instrument settings so switching between guitar and bass takes one tap, not a settings dive. Alternative tunings are available for when you switch to open or alternate-tuned guitars mid-set. Pedalboard layout lets you organise your preset list to match your physical setup. • Giant-display chromatic readout — readable from stage position • Instrument presets: switch between guitar, bass, and others in one tap • Stage-optimised design: high contrast, large needle, clear in any light • Alternative tunings for open and alternate-tuned instruments • Pedalboard layout for organising presets to match your setup • Subscribe monthly or pay once — either unlocks preset memory, alt tunings, and pedalboard layouts Runs on-device.
