Versatile Bass Multi-Effects Pedal

The Zoom B1X Four delivers over 70 effects and nine amp models in a single floor unit. Bassists can chain up to five effects simultaneously and store them across 50 user presets. An integrated expression pedal adds real-time control for volume, wah or modulation. The package includes a charger and straps for immediate use.

Powered for Extended Sessions

Four AA batteries, USB or the supplied AC adapter provide up to 18 hours of continuous operation. No fan or active cooling is mentioned, so the unit runs silently on stage or in the studio. The efficient design avoids mains hum and keeps the pedalboard tidy without a bulky power brick.

Connected for Live and Studio Work

A 1/4" input accepts both active and passive basses, while a 3.5 mm aux jack lets you play along with backing tracks. The amp/headphone output serves stage monitoring and silent practice equally. USB connectivity enables deep editing via ZOOM Guitar Lab software. The built-in looper captures 30 seconds or 64 beats, synced to 68 rhythm patterns.

Questions about this item

How do I power the B1X Four and what is the common mistake?

Power it with four AA batteries, USB, or an AC adapter; the step people miss is selecting the correct power source in the global settings so the pedal does not shut down unexpectedly.

What will need replacement after extended use of this pedal?

The four AA batteries will need replacement after roughly 18 hours of continuous play, and the integrated expression pedal may eventually require servicing if the mechanism wears.

What limit appears first when I run long sessions on batteries?

Battery life caps uninterrupted use at about 18 hours before the four AA cells must be swapped or you must switch to USB or AC power.
