Adjustable strings and an extra thick wooden sound port ring for bass compression gives the Sequiriya Line a wide dynamic range of highs and lows. Two sets of eight micro-coiled metal cajon strings give a snapping snare effect and are adjustable with the included tuning key. These strings are hand wound in the style of master cajon builder, José "Pepote" Hernández Diaz and respond with the upmost sensitivity. The 9-Ply, 12mm thick Baltic Birch resonating body develops the sound into a full, punchy tone that projects with clarity and warmth. A decorative wood inlay adds a touch of elegance to their appearance. Made in Spain.
