Details

Overview

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. Tones of 1964 still ring in this vintage voiced speaker; 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.
