About Quarterman Res-O-Cones-

The Quarterman Res-O-Cone is the"Heart of the Sound” in a resonator guitar. Just having a plain spun or stamped cone is not any guarantee you will have a great sounding instrument. It has to be the well made hand-spun Dobro-style or National-style resonator cone, such as those made by J.P. Quarterman. Made from hand-spun special aircraft-grade aluminum & crafted to the precise thickness & weight tolerances (as specified by inventor John Dopyera) to produce the optimum tone & volume, that has made the Quarterman name famous. He’s now pressing the brass washer on his Dobro-style cones with Res-O-Cone, JPQ & Co., and stamping the center of his National-style cones with Res-O-Cone, JP Quarter & Co., in order to authenticate them; because it's noted and rumored that some other ambitious resonator builders were selling their cones using his brand name (often imitated, but never duplicated). Replacing your cone with a Genuine Quarterman Res-O-Cone will give any resonator instrument, including yours, improved tone quality and power. Acclaimed by top luthiers & pro players, as best in the world. Made in the USA.
