Internal and external maintenance was completed in January 2023. It's a Lancaster equipped with a 12 inch Monitor Gold. The small feel of the high-efficiency 12-inch unit and the hole tone that sounds throughout the box are unique to this model. It is one size smaller and easier to sound than RECTANGLAR, and is compatible with tube amplifiers (Tomoho Asaine)
