Conventional external expression pedals often control only parameters of an effects unit, requiring the use of switches on the effects unit to change its status. Ampero II Press solves this problem perfectly with its built-in single footswitch. And the optimized footswitch structure provides the excellent tactile feedback. Designed with a passive circuit, it's reliable and convenient. Whether on stage or in the studio, Ampero II Press is ready to add extraordinary expressiveness to your performance. Ampero II Press adds a switching function on top of its expression capabilities, following the design of traditional single pedals. By stepping on the front end, you can trigger the footswitch to directly switch the operating status. This eliminates the cumbersome process of using an effects unit's footswitch for switching, as required by conventional expression pedals. Compared to conventional expression pedals, Ampero II Press provides the most convenient and user-friendly experience.
