Compact strobe tuner with identical ±0.02 cent accuracy as ST-300, five temperaments, and drop tuning in a smaller footprint.

The Turbo Tuner ST-300 Mini delivers the same professional ±0.02 cent strobe tuning accuracy as the full-size ST-300 in a compact pedalboard-friendly format. Despite being smaller than most mini tuners, it maintains the bright LED display with excellent outdoor visibility. Features five programmable temperaments, drop tuning capability, and multiple tuning modes including an open tuning mode that displays string numbers instead of note names. The tuning range spans C0 (16.35 Hz) to C8 (4,186.0 Hz). Constructed with a rugged metal chassis weighing just 153g (5.4 oz). Powered by 9V DC only at 50 mA consumption - no battery compartment to save space. Note that unlike the full-size version, the Mini lacks the always-on pass-through mode and power output for daisy-chaining. Ideal
