Questions about this item

How quiet is the Zoom B1 Four during long rehearsals?

The unit weighs 1.42 kg and has no internal fan, so it runs silently; only the footswitch clicks are audible.

What cables and power source does the Zoom B1 Four require?

Connect your bass with a standard instrument cable to the input and route the output to your amp or DI; power comes from the included 9 V DC adapter.

Can the Zoom B1 Four sync with my older drum machine via MIDI?

There is no MIDI port, so the 68 built-in rhythm patterns run independently; you can still play along by matching tempo manually.
