Eminence GA-SC64: 12″ Guitar Speaker by George Alessandro

Vintage American ceramic magnet tone approved by legendary amp builder, George Alessandro. Well-balanced from top to bottom with tight, full lows, warm mids, and warm, but open highs.

Eminence and 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. “The early 1960’s was a time when things were simpler. Studios were recording with one or two analog tape tracks. Stereo records were high tech, and hum canceling pickups were still awaiting a patent.” said George Alessandro, President, Alessandro High-End Products. “The warm, full character of the GA-SC64 brings you back to those days when used in vintage amps. While many things have advanced in 50 years, the tone of 1964 still rings true with this unique guitar speaker.”
