Compact yet overly capable, the On-Stage GTP7000 Mini Pedal tuner smoothly and stably integrates with your effects board, occupying minimal space. This chromatic mode tuner with 430–450Hz pitch range and +/- 0.5 cent tuning tolerance is powered by a 9V DC adapter. The oversized, high-visibility four-color regular, strobe or half strobe display provides easily read note name indication, while true-bypass circuitry ensures absolute signal integrity.
