Peterson 403884 StroboStomp HD Strobe Pedal Tuner

The Peterson 403884 StroboStomp HD is a professional strobe pedal tuner offering 0.1-cent accuracy, a large 417-segment high-definition LCD, and more than 135 Sweetened and Guided Tunings. Designed for pedalboards and stage use, it combines fast visual tuning with true bypass, buffered output, and always-on monitor operating modes.

Guitarists, bassists, and multi-instrument performers can use the StroboStomp HD for standard tuning, alternate tunings, drop and capo setups, and instrument-specific Peterson Sweeteners. Its variable-color LED backlight can be customized for visibility or assigned to individual presets, while the display remains readable in direct sunlight. Unlimited user presets and Peterson Connect compatibility support personalized professional workflows.

The stainless-steel pedal accepts a 1/4-inch mono input and output and operates from an included 9V battery or optional regulated 9V DC power. A dedicated 9V DC output can supply up to 1A to another compatible pedal when an adequately rated external supply is used. Micro-USB connectivity enables firmware updates and Peterson Connect configuration.
