GA-SC64
Tones of 1964 still ring true in this
vintage voiced speaker by seasoned
amp guru George Alessandro. 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.
