This vintage-sounding Eminence speaker was designed in collaboration with amp guru George Alessandro. The result: an unmistakably punchy and musical speaker.

Eminence GA-SC64 Guitar Speaker
Following the successful collaborative effort on the Eric Johnson Signature EJ1250 guitar speaker, Eminence Speaker and amp guru George Alessandro have teamed up once again to develop a 12" guitar speaker with vintage sounds circa 1964, the GA-SC64. Well-balanced from top to bottom, the GA-SC64's warm, dynamic character lends itself to vintage amps as well as modern gain and distortion. The traditional build materials offer warmth, dynamics, low note articulation and proper distorted harmonic content layering.
