Bass Multi-Effects Processor for Direct Recording

The Zoom B2 Four is a bass multi-effects processor built for players who want amp modelling, IR loading and a looper in one pedalboard unit. It offers 104 effects with up to five running simultaneously plus six DI models and multi-layered IRs. A 60-second looper and rhythm machine support practice and solo performance. 24-bit A/D and D/A conversion with 32-bit DSP handles the signal path.

Balanced XLR Out and Ground-Lift for Stage Use

A balanced XLR output with a ground-lift switch connects straight to a mixing desk without a separate DI box. Quarter-inch input and output handle standard instrument cables while a 3.5 mm auxiliary input and headphone output cover silent practice and playback. The pedal runs from the included AD-16 AC adapter so no battery compartment adds bulk. Lightweight construction keeps the board portable for gigging musicians.

Check Your Signal Chain and Power Before Buying

Verify that your amp or audio interface accepts a line-level signal from the XLR or quarter-inch outputs. Confirm you have a free mains socket for the AD-16 adapter because the unit does not run on batteries. Ensure your pedalboard layout has space for the processor and that you can reach the footswitches comfortably. Buyers who need more than five simultaneous effects or longer loop time should look elsewhere.

Questions about this item

What does the balanced XLR output with ground-lift switch provide for direct recording?

The balanced XLR output with ground-lift switch allows direct connection to a mixing console or audio interface while eliminating ground-loop hum, delivering a clean signal for live sound or studio recording without a separate DI box.

What power supply is required and how is the pedal powered?

The included AD-16 AC adapter powers the unit; no battery compartment is present, so mains power via the supplied adapter is the only way to operate the processor.

How do you record directly to a computer using the USB audio interface function?

Connect the USB port to a computer; the processor appears as a 24-bit / 32-bit DSP audio interface, allowing direct recording of the processed bass signal into any DAW without additional drivers on most operating systems.
