Totally Wycked Audio (TWA) is proud to announce the release of the Source Code™ next-gen soft-clip Overdrive. The TWA Source Code is the ultimate evolution of the iconic TubeScreamer, and was designed by none other than Susumu Tamura, the creator of the legendary TS808 circuit. Condensing Tamura-san’s 50+ years of experience in the field of overdrive design into a single, powerful package, Source Code reimagines the classic TS circuit that so many love (and some love to hate!) and launches it into the future. Since 2021, Tamura-san has been carefully analyzing every aspect of his enduring soft-clip circuit to optimize its performance. Source Code builds upon the strengths of that classic “green box” while offering novel improvements that enhance the original circuit & expand its capabilities.
