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 autosave 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.
