The ZOOM B1 FOUR and B1X FOUR are designed to elevate your bass tone, offering over 70 effects and amp models, a built-in looper, and an integrated rhythm section. With access to ZOOM Guitar Lab, you can create, edit, manage, and download additional effects and patches to fully shape your sound.
Both units feature nine amp models that recreate classic bass rigs and allow you to run up to five effects simultaneously, chained in any order. The B1X FOUR version includes a built-in expression pedal, giving you hands-on control over any effect or parameter. The looper enables recording of up to 30 seconds or 64 beats of CD-quality audio, complemented by 68 rhythm patterns for practice, songwriting, and performance.
You can store your custom sounds in 50 user memory locations, with an Auto Save function that automatically remembers all parameter settings. The PRESELECT function allows you to silently choose your next patch without interrupting your current sound, and the onboard chromatic tuner ensures accurate tuning at all times.
The B1 FOUR and B1X FOUR support both active and passive bass guitars, include an auxiliary input for connecting external music players, and provide an output jack for use with an amplifier or headphones. Lightweight and compact, they easily fit into a gig bag and integrate seamlessly into any pedalboard setup. Power is supplied by four AA batteries for up to 18 hours of use, or via USB, which also enables firmware updates and connection to ZOOM Guitar Lab.
