Ernie Ball Volume Pedal Jr. Pedal with Built-In Tuner

Enjoy the same rugged construction and time-tested performance as Ernie Ball's traditional volume pedal PLUS an enhanced definition digital tuner pedal. | Save space and simplify your pedalboard with this unique 2-in-1 pedal for guitar or bass. | In the heel down position (volume off), the display automatically enters tuner mode, offering a smooth, accurate, and visually pleasing tuning experience. | As foot sweeps forward, the vibrant screen conveniently displays your volume level. | Display can also be set to volume only or tuning only. Simply double tap the touchscreen to select between modes. | The mono input jack can accept both passive and active mono audio signals with 9 to 18 volts of headroom (depending on the power supply), making it an ideal tuner pedal for both bass and guitar. | Pedals are set to the standard 440 Hz, but reference pitches from 432 Hz to 447 Hz are readily available via the touchscreen.
