The VPJR Tuner pedal combines Ernie Ball�s world-renowned volume pedal with an enhanced definition digital guitar tuner. In the heel-down position, the pedal�s vibrant touchscreen automatically enters tuner mode, allowing for silent tuning. As the foot sweeps forward, the screen switches to volume mode, providing a graphic display of your volume level. Alternatively, the screen can remain in volume mode or tuner mode, regardless of the pedal�s position in the sweep. Simply double tap on the touchscreen to toggle between modes. The VPJR Tuner provides the same rugged construction and time-tested performance as Ernie Ball�s traditional volume pedal, resulting in the most useful guitar tuner pedal on the market.
