Critic Reviews

Zoom B2 Four: An In-Depth Review (2/14/24) |

jonstubbsmusic.com

The Zoom B2 Four offers a solid array of effects and amps, ideal for bass players seeking versatility on a budget. While its sound quality and patch memory impress, the device suffers from a few notable flaws: buttons are awkward to access with feet, certain effects lack depth, and some modules introduce noise. The absence of dedicated patch-level settings and the quick disappearance of knob display values are also detractors. Overall, it’s a mixed bag—great for those looking for straightforward functionality, but it may frustrate those seeking deeper control or customization.
