This is an early 1960's Silvertone made by Harmony of Chicago. This is a similar to a Les Paul. This guitar is part of Harmony's Stratotone line. It has DeArmond pick ups, mother-of-pearl inlays on neck, and the "Blender" control which regulates the bass and treble pick ups. The original tuners have been replaced but it plays and holds tune better for it.
