If you're looking for a compact expression pedal, the BOSS EV-30 is the best choice. Thanks to its compact dimensions, it fits perfectly into crowded pedalboards, while the robust aluminum housing in proven BOSS quality withstands even the toughest rock performances. The innovative internal mechanism of the EV-30 offers super-accurate and smooth control over all parameters, comparable to large-format pedals. With two expression outputs, you can control two different devices with just one pedal, saving additional space. The outputs are electronically isolated, protecting against unwanted noise from ground loops. The EV-30 allows real-time parameter control of many compact pedals with expression pedal inputs. It is also perfect for use with multi-effect processors and effect switchers. The polarity switch enables the use of the EV-30 with nearly all devices that have expression inputs, including keyboard instruments and synthesizers.
