A limited edition "Premium Collection" with only one bottle produced. The "Premium Collection" is a special lineup where every instrument is unique. Each instrument is one of a kind, crafted from carefully selected wood and coloring that reflects the sensibilities of the artisans.・"Ironwood," Ironwood is an extremely dense hardwood, and as its nickname "ironwood" suggests, it boasts overwhelming durability. However, it is not easy to process, but the craftsmen at the Asuka factory finish it with high precision and care. • Kalimantan Ebony Fingerboard: Kalimantan ebony is sourced from the Indonesian island of Kalimantan and is a much denser, heavier, and more durable wood than typical ebony. This specification is not available in the regular lineup and is only possible with this show model.・Mojotone Classic 5string Jazz Bass We selected Mojotone, a hand-wired pickup manufacturer based in North Carolina, USA.
