Zoom B1X Four Bass Multi-Effects Pedal with Expression Pedal

The Zoom B1X Four is a versatile multi-effects processor designed for electric bassists, featuring an integrated expression pedal for real-time, variable control over select effects. Housed in a compact and user-friendly stompbox format, it provides a wide array of effects, bass amp simulations, and performance tools such as a built-in chromatic tuner and a 30-second looper. With 68 onboard rhythm patterns, you can easily add drum grooves during practice or looping sessions.

This pedal includes effects like distortion, chorus, and modulation, along with nine bass amp models that emulate classic setups. The expression pedal allows for smooth, dynamic control over these effects. You can also adjust pedal behavior digitally through the B1X Four’s display for a customized feel and performance.
