Description
Meet the Harley Benton Powerplant Tuner Junior, a compact yet powerful addition to your pedalboard that combines precision tuning and robust power supply functionality. Whether you're a guitarist or bassist, this pedal ensures your instrument stays perfectly in tune while simultaneously powering your other pedals, making it an essential tool for both stage and studio setups.
This chromatic floor tuner is equipped with a large LC display for easy readability, even in dimly lit environments. Its true bypass design ensures that your tone remains uncolored when the pedal is disengaged, preserving the integrity of your sound. The tuning range spans from 12 to 4186 Hz, providing exceptional versatility, while the ± 1 cent accuracy guarantees precise tuning for every performance.
Beyond tuning, this pedal acts as a multi-power supply, featuring eight outlets with various capacities to accommodate different pedal requirements. Six of these outputs provide 9V at 100mA, while two deliver 9V at 500mA, all with isolated sections to prevent unwanted noise. With a total output of 1600 mA, short circuit, and over-voltage protection, the Powerplant Tuner Junior ensures that your gear remains safe and sound.
