TWA Source Code—Next Evolution of the 808

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, top-mounted jacks, and true bypass switching, the Source Code is pedalboard-friendly and road-ready. Power it with a standard 9VDC supply or battery, and step into the future of overdrive.

Key Features:

  • Next Gen 808-style overdrive designed by Tube Screamer creator Susumu Tamura.
  • All-new 18V operation via internal voltage inverter for improved operation and increased headroom.
  • All-new multi-transistor input buffer circuit to preserve original guitar tone accurately.
  • "Magic IC" OpAmp for increased harmonic content and more amp-like feel.
  • All-new "BITE" control adjusts amount of integer harmonics generated by circuit.
  • +6 dB boost circuit for increased output level without altering tone.
  • Standard DRIVE, TONE, and LEVEL controls.
  • External 9VDC or 9V battery operation.
  • Top-mounted jacks for easier implementation on pedalboards.
  • Low-profile, matte finished machined aluminum knobs for precise adjustments.
  • Mechanical True Bypass switching.
  • Handmade in USA.

The TWA Source Code isn't just another overdrive — it's the new standard in the 808 legacy.
