There are two models of DrumBox: model I and model II.
The difference between them is in the bass response. DrumBox I has a bass like that of a cajon and DrumBox II has a bass like that of a bass drum. DrumBox I is the simple version while DrumBox II is more advanced. To hear the difference check the videos below.
The amplification of the DrumBox works like that of an electric guitar. The signal coming out needs a preamp to be able to be heard. Plug the DrumBox into a mixer or a guitar amplifier or other powered amplifier to hear how it sounds through the pickups. You can also use an audio interface for this. The amplification is completely passive, no batteries are needed.
