Sound City Mod preset

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

The Sound City Mod is a modified or special-configuration variant of the standard Sound City 100 circuit, reflecting the company's practice of offering circuit modifications and alternative configurations to professional clients. Dallas Arbiter's relationship with touring professionals led to a range of non-standard builds that tailored the Sound City character for specific applications, such as modified input sensitivity, alternative tone stack configurations, or adjusted output stage bias. The Mod designation on a Sound City schematic typically indicates a departure from the standard production circuit in one or more significant areas.
