Introducing the B2 FOUR Amp and Effects Emulator, powered with Zoom’s Multi-Layer IR technology and 6 iconic DI models. Now you can craft the perfect low-end tone.

Build patches from 104 effects, including models of famous boutique effects and preamps. Mix and match up to 5 effects and amps simultaneously to build your own custom patches.
When you need to plug directly into the house PA, the lightweight and portable B2 FOUR has you covered. It features six DI models that recreate the tone of world-class direct boxes.
Preloaded with 250 presets, these patches are designed to give bassists the ability to recreate the sound of popular songs from the 50’s to today.
Jam and rehearse with the B2 FOUR. The 60-second looper allows you to build grooves, while the 68 rhythm patterns from the on-board drum machine are the perfect companion for practice.
A balanced output helps you connect directly to a PA or interface while the stereo outputs can connect to an amp. The instrument input has a switch to change the impedance from 1M to 10M ohms, giving you a cleaner tone for upright basses equipped with piezo pickups.
The B2 Four can be used as a 2-in/ 2-out audio interface by connecting to a computer or smartphone with your favorite effects and amp models.
