Fender Pro 6G5A preset

Close · 70/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Fender Professional 6G5A is the A-suffix revision of the brown-era 6G5 Pro, incorporating minor circuit refinements that finalize the brown-era Pro design ahead of the blackface transition. At 40 watts with 6L6GC output tubes, the 6G5A provides ample clean headroom for medium to large venues. The brown-era voice balances warmth from the tweed heritage with the increasing clarity and definition that defines the 6G-prefix family. This is one of the final brown-era Pro designs before Fender launched the blackface AA763 circuit in 1963. This entry represents the general 6G5A without a specific document suffix.
