The most visually striking addition to the Cajon Fineline series is the smooth, rounded resonance box. This design guarantees a comfortable and enjoyable playing experience for the musician. The resonance box also supports the distinct sound characteristics of the Morado and Mocca's playing surfaces, which are made from peeled high-grade woods. Snare wires developed specially for each of these two playing surfaces add a distinctive note to the sound and give the instrument an incredibly delicate response. In short, the Cajon Fineline series' unique overall aesthetic offers convincing design and sound quality.
