Zoom B2 Four Bass Guitar Multi Effects Unit

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.

Zoom’s innovative Multi-Layer IR technology recreates the tonal characteristics of playing through classic amps and cabinets. These impulse responses were captured from cabinets at 3 different levels and are activated based on the volume of your bass.

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.

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. 

With a constantly expanding library of patches and effects, bassists can continue to expand their sound with the "Handy Guitar Lab for B2 FOUR" app (for iOS), available to purchase on the Apple App Store.
