Zoom B1X Four Bass Multi-Effects Processor with Expression Pedal

The Zoom B1X Four is the bass multi-effects processor that serious players in Kenya have been waiting for. Compact enough to fit in your gig bag, powerful enough to replace a full pedalboard — this unit does not compromise.

You get 70+ built-in effects covering distortion, modulation, delay, reverb, EQ, and beyond. Stack them, chain them, shape them to your session. Whether you are tracking in a studio, rehearsing at home, or running direct to a PA on stage, the Zoom B1X Four gives you the tonal range to handle it.

The integrated expression pedal is what separates this unit from the standard B1 Four. Control volume swells, wah, pitch shifts, or any assignable effect parameter in real time — hands-free, no extra hardware needed.

13 amp and cabinet models let you dial in authentic bass tones without hauling a rig. The built-in looper gives you up to 30 seconds of phrase recording for live layering or practice. The 68-pattern drum machine keeps your timing locked whether you are woodshedding or writing new material.

Patch management is straightforward: 50 factory patches and 50 user slots, all editable and recallable instantly. USB connectivity handles firmware updates and patch transfers without fuss.

Battery life is rated at up to 18 hours on 4 AA batteries — a legitimate all-day rehearsal or gig companion. An AC adapter is also supported for studio or fixed-rig setups.

At Zamar Audio Solutions, every Zoom B1X Four ships with a 12-month local warranty. Pay via M-Pesa or card at checkout. Same-day delivery available across Nairobi, with regional shipping to the rest of Kenya.

This is not a beginner toy. It is a working tool for bassists who need flexibility, reliability, and real sound — without the bulk.
