What it is

The B1X Four is a bass multi-effects processor from Zoom. It is the expression-pedal version of the B1 Four, which Zoom sells without the pedal. Both units offer a looper, a built-in rhythm section, and amp and cabinet models. The manufacturer describes the effects library as over 70 on the B1X Four, against over 60 on the B1 Four. Retailers commonly list it as 70+ effects. The main difference from the B1 Four is the expression pedal, which the manufacturer says can control effects such as volume, wah, and pitch. The B1X Four is also wider and heavier, which reflects its larger footprint with the pedal. Its PRESELECT mode switches patches silently, and its STOMP mode toggles individual effects, which the manufacturer presents for live use. Zoom's listing places the product among its bass-focused pedals. Price on the manufacturer page is 119.99 US dollars for the B1X Four, against 99.99 for the B1 Four. Availability on the manufacturer page showed as unavailable with preorder messaging at the time of research, so the current status may differ.

How it's used

Musicians generally use the B1X Four as a bass pedal on a pedalboard or as a desktop unit lifted off the floor. Retailers and reviewers also describe it for practice and portable use, running on batteries, through headphones, or in a gig bag. For live work, the PRESELECT and STOMP modes are presented for patch switching. The looper can be combined with the 68 rhythm patterns for songwriting or improvisation. The expression pedal can be assigned to volume, wah, delay, or pitch.
