Recording King's RM-991 classic metal body tricone resonator has three 6" Recording King cones that transfer incredibly loud tones through the body of the guitar. The RK hand-spun aluminum resonator cones are positioned with two on the bass side and one on the treble side, giving an EQ balance with a sweeter, warmer sound. It also features a roundneck.

The RM-991 tricone resonator is made from nickel-plated bell brass and features a screen coverplate and sandcast powder-coated T-shaped bridge with an ebony and maple saddle. The bridge is connected to the center of each cone so that when the strings are hit, the vibrations run through the saddle and then into the bridge. An open-pan soundwell helps this tricone produce notes with bell-like clarity and long sustain characterized by chiming overtones and a natural ambiance—exactly what you are looking for in a resonator.
