Bigger, bolder Bass - B1 FOUR / B1X FOUR Multi-effects Pedals for Bass!

The Zoom B1 FOUR and B1X FOUR take you to new heights with over 70 effect and amp models, a looper, and a built-in rhythm section. Plus, you can access the additional library of downloadable effects from ZOOM Guitar Lab.

X Stands for Xpression

For extra control, the B1X FOUR offers an expression pedal that lets you adjust effects like volume, wah, delay, and pitch.

Beyond the Bass-ics

Create your unmistakable sound with over 60 traditional and boutique effects like octaver, bass synth, and fuzz.

Classic Amps

With 9 classic amps and cabinets like Fender, Ampeg, Aguilar, and more, you can replicate your stage sound.

Free Guitar Lab Software Included

Discover an endless world of patches, effects, and more from artists with ZOOM Guitar Lab. Manage and back up all your patches to experiment and create endless combinations.

Your New Rhythm Section

Play your bass with 68 different drum patterns! The B1 FOUR series offers a built-in drum machine with various rhythm patterns in 4/4, 3/4, and more.

Looping Dynamics

Set a bassline for up to 30 seconds and endlessly build your performance to create a dynamic, multi-part arrangement.

Zoom Is Your Backup

Activate the auto-save function and your patches and level settings are instantly saved as you create.

Live Performance

Use one of two performance modes to switch patches and effects seamlessly during live shows. In PRESELECT mode, jump from patch to patch without affecting the current sound. STOMP mode lets you turn individual effects on and off.

A Practical Approach

Place your pedal on the floor or desktop and simply dial in your desired tones and settings.

Power Options

The B1 FOUR / B1X FOUR can run on four AA batteries. You can also use an optional Zoom power supply AD-16 or power the pedal via USB bus.

How will you dial in your tone?

So for the price I was extremely positively surprised by the workmanship and performance. I use the effect unit for practicing at home. With a 46 Ohm headphones, the device is sufficiently loud. Many standard effects and amp simulations are available, which can be combined and stored as desired. Super!
