Replogle Resonator cones are hand-spun in California to exacting specifications and high tolerances. Mike Replogle uses a special hardened aluminum alloy for maximum strength, tone, projection and sustain.

These are the exact cones used since the mid-1990’s in US-made Dobro-brand guitars produced by the Original Musical Instrument Company (OMI) and the Original Acoustic Instrument (OAI) company under Gibson. Until recently Replogle cones have only been available directly to custom builders and manufactures and have been used by OMI, OAI, Gibson, Scheerhorn, Crafters of Tennessee, Beard, Owens, Wechter, Weber, and Regal (Saga Music) among others. Now, these “Original Equipment” cones are available directly to individual players and builders.

Spider Resonators

These double-spun inverted-cone design resonators are matched with the spider bridge, creating the resonator assembly that forms the sound engine that has been driving the Dobro sound since 1928. This is the sound of the lap slide style of playing, prevalent in Bluegrass and Country music.





Biscuit Cones


Large format biscuit cones have been a standard in the Triolians, Duolians, and other models since the early 1920’s. Models include both wood and metal body designs, and are used extensively in bottleneck blues, delta blues and other slide styles.




Replogle Tricones- Set of 3


The original resonator design used  with the first metal National guitars, Tricones have been a standard model since the early 1920’s. Models include primarily metal body designs, and are used extensively in bottleneck blues, delta blues and other slide styles.
