Tube 1 for rich harmonics and thick low frequencies.
Tube 2 for a clear attack and tight low frequencies.
Tube 3 for a clear and glossy sound.
Solid State 1 for moderate compression and sharp tones.
Solid State 2 for a clear tone and little distortion.
Solid State 3 for elevated mids and low treble to replicate the Motown sound

HISTORIC BASS SOUNDS
Preloaded with 250 presets, these patches are designed to give bassists the ability to recreate the sound of popular songs from the 50’s to today.
NAVIGATE AND CREATE
The 4 rotary encoders allow for quick adjustments to effects parameters as well as output settings. The cross key navigation buttons help you control the pedal with ease.
LOOP AND GROOVE
Jam and rehearse with the B2 FOUR. The 60-second looper allows you to build grooves, while the 68 rhythm patterns from the on-board drum machine are the perfect companion for practice.

INPUT & OUTPUT OPTIONS
A balanced output helps you connect directly to a PA or interface while the stereo outputs can connect to an amp. The instrument input has a switch to change the impedance from 1M to 10M ohms, giving you a cleaner tone for upright basses equipped with piezo pickups.
The B2 Four can be used as a 2-in/ 2-out audio interface by connecting to a computer or smartphone with your favorite effects and amp models.
Its Own App
With a constantly expanding library of patches and effects, bassists can continue to expand their sound with the "Handy Guitar Lab for B2 FOUR" app (for iOS), available to purchase on the Apple App Store.
Features clean bass and bright high frequencies.

NEW PREAMP MODELS
This original ZOOM Clear DRV preamp uses a linear phase filter in the distortion path. As a result, phase interference is eliminated during dry mixing, providing a clear drive.
Super Low Preamp
