Schlagwerk CBT 10 - The new Cajon Bass Tube provides a rich bass drum sound. And it couldn't be easier: simply slide the Cajon Bass Tube into the rear sound hole and that's it. No screwing or gluing together necessary. From now on palpable and powerful low frequencies can be produced. At the same time, the Cajon Bass Tube generates the typical drum-like distinction between snare and bass range. The Schlagwerk Cajon Bass Tube is optimised for all Schlagwerk cajons, but can also be used on all other cajons with a sound hole diameter of approx. 12cm.
