The EV-30 Boss Expression Control Pedal combines a space saving pedal design with a rugged and hard-wearing die-cast aluminium construction. This small-footprint expression pedal is right at home on small or busy pedalboards. Even though the EV-30 is small, the die-cast aluminium enclosure ensures that it will survive for years to come. The action of the internal mechanism on the Boss EV-30 Expression pedal is designed to be perfectly smooth, so you can be sure your parameter control will be completely accurate. The space saving design is not just limited to its size, as the EV-30 has dual electronically isolated expression outputs, granting you the ability to control two devices with a single expression pedal.
