Adjustable strings and an extra thick wooden sound port ring for bass compression gives the Seguiriya 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 wooden inlay adds a touch of elegance to their appearance.
