ZOOM B1 Four

The Zoom B1 Four is a multi-effects processor designed for use with electric basses. Offered in an easy to use stompbox format, the B1 Four sports a wide selection of effects, amp emulations, and other features, such as an onboard 30-second looper and a chromatic tuner. With 68 built-in rhythm patterns, you can add drum loops to the mix, which can be quite helpful during looping.

Packed with features for the modern bassist

The Zoom B1 FOUR’s onboard drum machine lets you play your bass to 68 different drum patterns in a variety of time signatures such as 4/4, 3/4, and more. For live performances, two performance modes allow you to switch patches and effects seamlessly. At home or in the studio, put your pedal on the desktop to easily dial in your sounds and settings — the auto save function instantly backs up your patches and level settings as you create them! The B1 FOUR operates on four AA batteries or the optional Zoom AD-16 AC adapter; you can even run your pedal via USB bus power.
