Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Gretsch 6152 was a Valco-manufactured amplifier in Gretsch cosmetics, positioned slightly above the 6151 in the Gretsch catalog hierarchy. Its all-valve circuit provided clean, uncoloured amplification suited to the bright, jangly sound of Gretsch electric guitars. The Gretsch-Valco relationship was one of the more durable OEM partnerships in mid-century American amplifier production.
