Peavey Classic20 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Peavey Classic 20 is a 20-watt all-tube combo built on EL84 output tubes, delivering a British-influenced chimey top end and compressed breakup that contrasts with Peavey's typically American-voiced catalog. Its small-wattage tube circuit is especially well-suited to recording, producing genuine power-amp saturation at manageable studio levels. The Classic 20 appeals to players who want the Peavey build quality with a more vintage, touch-sensitive tube response.
