Sound City City 100 Dr114 preset

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

Sound City was a British amp brand manufactured by Dallas Arbiter in the late 1960s and early 1970s, sharing DNA with Marshall thanks to transformer designs from Jim Marshall himself. The 100-watt head delivers a bold, punchy British crunch with thick midrange and excellent harmonic saturation. These amps were favored by touring acts who needed reliability and raw power on stage.
