Model 633/633E


The Roots of Rock...Unplugged

Originally manufactured by Harmony, the 633 ‘Sovereign’ made its stamp on rock n roll history via greats such as Pete Townsend and Jimmy Page. We modeled the 2015 reissue from our in house 1964 Sovereign.

The Sovereign is the ‘Big Daddy’ jumbo of the Silvertone acoustic family and is certain to be appreciated for its loud volume and deep tone just the same way it was back then. Like the 600 model, the Sovereign features a solid Engelmann Spruce top and Mahogany back and sides for a well balanced and articulate sound.

The old ‘steel reinforced’ neck has been replaced with a modern two way adjustable truss rod and a C-shape neck profile. The 600E version has a built in Fishman® Clearwave60 preamp with built in tuner.
