PG contributor @TomButwin dives into the latest evolution of the green-box legacy: the TWA Source Code SC‑01 Overdrive. Designed by the legendary Susumu Tamura (yes—the original mind behind the TS808), this pedal combines vintage tone and handmade USA craftsmanship with serious modern enhancements: internal 18v voltage-boosting circuitry for extra headroom, a multi-transistor input buffer to preserve your guitar’s core tone, and a unique “Bite” control for dialing in even-order harmonics and amp-style saturation.
