TWA SC-01 Source Code Overdrive

The Tube Screamer. Love it or hate it, it is a staple of the overdriven effects world, and a piece of gear used by thousands across the globe for over 40 years. Perhaps the most famous model is the TS808, and it has something uniquely in common with today’s pedal: they were BOTH designed by the same person. The TWA (Totally Wycked Audio) SC-01 Source Code Overdrive comes to us via our friends at Godlyke, and it meshes old school and new tech into one beautiful amp-driving machine…

The TWA Source Code is the ultimate evolution of the iconic Tube Screamer, designed by none other than Susumu Tamura, the creator of the legendary TS808. Built for players who demand more from their overdrive, the Source Code preserves the soulful midrange warmth of the classic green box while unlocking a new dimension of clarity, headroom, and harmonic richness. Powered by an internal voltage regulator, the Source Code runs at 18V for dramatically improved dynamics and increased headroom. Its multi-transistor input buffer ensures your guitar’s natural tone stays intact, while the exclusive “Magic IC” OpAmp injects extra harmonic content and an amp-like feel that responds to your touch.

Adding to its arsenal, the Source Code features a unique “Bite” control, letting you dial in the amount of even-order harmonics for everything from smooth, singing leads to aggressive, cutting drive. A built-in +6 dB boost circuit delivers extra output without changing your tone — perfect for solos or pushing your amp harder. With classic Drive, Tone, and Level controls, the Source Code has great range and is pedalboard-friendly and road-ready. Power it with a standard 9VDC supply or battery, and step into the future of overdrive.

Handmade in the USA, the SC-01 Source Code Overdrive also features top-mounted jacks for easier implementation on pedalboards, low-profile, matte finished machined aluminum knobs for precise adjustments and mechanical True Bypass switching. Bringing legendary, vintage sound into the modern era, this green beast will drive your amp in more ways than you can count.
