Susumu Tamura Source Code Evolved Tube Screamer
The TWA Source Code Overdrive is hailed as the next evolution of the iconic Ibanez TS808 Tube Screamer, designed by its original creator, legendary engineer Susumu Tamura. Leveraging over 50 years of experience, Tamura-san refined the classic soft-clip circuit to meet the demands of modern players, focusing on improved harmonic behavior and richer pick dynamics. Engineered by Totally Wycked Audio (TWA), the pedal features an internal voltage regulator that boosts standard 9V power to 18V for increased headroom and clarity, providing clearer note definition even with high drive settings. A multi-transistor input buffer ensures the preservation of the guitar's natural tone. Key features include a unique "Bite" control that allows users to dial in even-order harmonics for aggressive, amp-like saturation not achievable with vintage Screamers, and a built-in +6 dB clean boost for stepping forward in a mix without altering the core tone. The Source Code is a versatile drive pedal for blues, rock, and high-gain modern sounds.
