B1X FOUR
$119.99Reference price
The B1 FOUR bass multi-effects processor with an added expression pedal, controlling volume, wah, pitch, and more while playing. It houses 71 effects and nine amp models faithfully emulating real hardware, with up to five effects at once. A 30-second looper and 68 rhythm patterns are built in, and four AA batteries power roughly 18 hours of use.
An entry-class bass multi with a built-in expression pedal
It shares the B1 FOUR's effects and amp model lineup and adds an expression pedal, sweeping volume, wah, and pitch continuously to widen expression while playing.
Expression pedal
Volume, wah, pitch, and other effects respond to the pedal while playing. Including the pedal effects, 71 effects are on board - six more than the B1 FOUR.
Nine amp models and effects
Nine amp models faithfully emulate hardware such as the Ampeg SVT and Fender Bassman 100. Effects including octaver, bass synth, and fuzz run up to five at once in any order.
Looper and drum machine
The 30-second looper syncs with the built-in drum machine for overdubbing effected phrases. 68 rhythm patterns cover rock through jazz.
Live features and power
MEMORY mode with preselect, STOMP mode, and an output EQ for room-matching tone are on board. Four AA alkaline batteries power roughly 18 hours, the tuner supports Low-B/Hi-C, and Guitar Lab adds effects.
