The B2 Four effect and amp emulator features Zoom's multi-layer IR technology and six iconic DI models. Shaping the perfect sound for the low-end has never been easier.

Create patches from 104 effects, including emulations of famous boutique effects and preamps. Mix and match up to five effects and amps simultaneously to create your own patches.

Each amplifier model is based on Zoom's innovative multi-layer IRs, which replicate the feel of classic amps and speaker cabinets through their sound characteristics. The impulse responses were captured at three level stages using legendary cabinets and are activated depending on the volume of your bass guitar.

The four endless knobs allow for quick adjustments of effect parameters and output settings. With the cross-arranged navigation buttons, you can easily control the pedal.

Jam and rehearse with the B2 Four. The internal 60-second looper lets you create your own grooves, while the 68 beats of the built-in drum machine provide the perfect accompaniment for practice.
