Welcome to guitar building! The resonator guitar described in these instructions is patterned in many respects after a late-1920s wood-bodied National Triolian. These instructions were written for a guitar kit that we no longer have in stock. However, we still carry many resonator guitar parts and supplies needed to build or repair this type of instrument.
