The Korena take

The BOSS EV-30 is a compact dual expression pedal for real-time parameter control. Its two expression outputs allow one pedal to control two devices, helping conserve pedalboard space, and the outputs are electronically isolated to avoid ground-loop noise issues. The internal mechanism is designed for smooth, precise movement, while the die-cast aluminum chassis provides the pedal's foundation. A polarity switch broadens its use with gear that supports expression control, including compatible BOSS compact pedals, multi-effects processors, and switching systems.

Strong match

Who this is for

  • Cramped pedalboards where one expression pedal needs to control two separate devices.
  • BOSS compact pedals, multi-effects processors, or effects switching systems with expression-pedal inputs.
  • Expression-control setups where electronically isolated outputs are needed to address ground-loop noise concerns.

Consider the trade-offs

When to look elsewhere

  • Devices that do not support expression control.
