Volume/Expression Pedal with Tuner (3 in 1), can be used for both stompbox and multi effects players.
For Stompbox players: Tuner Press has 3 functions( Volume, Expression, Tuner). It can help save the pedalboard's weight, space, power supply qty and also budget. Meanwhile, it can work great with other stompboxs that have exp jacks.
For Multi effects players: Tuner Press has an Exp output, output jack and an individual footswitch to switch pedal's working mode. Players can switch expression or volume control at any time with the footswitch on Tuner Press. Besides, it uses our new generation tuner algorithm which makes tunning more accurate and sensitive than present multi effects( Including Ampero Series).
