The new Cajon Bass Tube provides a rich bass drum sound. And it's so simple: push the Cajon Bass Tube into the sound hole at the back - done. No screwing or gluing required. Low frequencies are already noticeably and impressively highlighted. At the same time, the Cajon Bass Tube produces the separation of the snare and bass ranges that is typical for drums. The Schlagwerk Cajon Bass Tube is optimised for all Schlagwerk Cajons, but also fits all other Cajons with a sound hole diameter of approximately 12 cm.
