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

The Recording King tricone is made from nickel-plated bell brass and features a 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. This tricone has a distinct tone and long sustain characterized by brilliant overtones and a natural ambiance only found in resonator instruments.
