The Urban OS Cajon series from Schlagwerk stands for "Open Sound & fully Screwed playing Surface". The fully screwed playing surface ensures an extremely direct snare response combined with a very open basic sound. During development, special vibration points were defined to determine the optimal screw positions. The OS series owes its open sound and excellent response to these. The interior of this Cajon series features side-mounted amplification strips that optimally support the assertive bass sound of the construction. The CP5230 Grunge Black Cajon reflects the used/street look visually as well as in the sound character. The instrument is designed for live use and delivers a bold, original overall sound that can assert itself very well even without additional miking.
