The Zoom B1 FOUR taked your low-end to new heights with over 70 effects and amp models, looper and a built-in rhythm section. Plus, access ZOOM Guitar Lab’s additional library of downloadable effects. Craft your signature sound with more than 60 traditional and boutique effects, such as octaver, bass synth and fuzz. Recreate your on-stage sound with 9 classic amps and cabinets like Fender, Ampeg, Aguilar and more.

ZOOM Guitar Lab offers an endless world of artist patches, effects and more. And with its ability to manage and backup all of your patches, you can experiment with endless combinations. Play your bass to 68 different drum patterns! The B1 FOUR series offers a built-in drum machine with a variety of rhythm patterns in 4/4, 3/4 and more. Lay down a bassline up to 30 seconds, and then endlessly overdub your performance to build a dynamic, multi-part arrangement. You can also turn on the auto save function and your patches and level settings will be instantly backed up as you create them.

Use either of 2 performance modes to seamlessly switch up patches and effects during live shows. PRESELECT mode lets you jump from patch to patch without affecting your current sound, while STOMP mode lets you turn individual effects on and off. Pick your pedal up off the floor for desktop use and easily dial in tones and settings to the exact levels you need, plus the B1 FOUR can operate with four AA batteries. You can also use an optional Zoom AD-16 AC adaptor or run your pedal via USB bus power.
