TWA Source Code
the Next Evolution of the 808

In 1979, Japanese electronics engineer Susumu Tamura designed the Ibanez TS808 Tube Screamer to compete with the Boss OD-1.

His unique soft-clip overdrive circuit went on to become one of the most copied, cloned, and modified guitar effects of all time.

Known for its midrange clarity and organic, tube-like tone, the “808” quickly became the amp-pushing pedal for countless guitarists - including a soon-to-be legendary blues player from Texas named Stevie Ray Vaughan.

Over the past four decades, the 808 has continuously evolved and spawned countless imitations across the gamut of pedal providers. 

But if you covet a modified 808, then why not go straight to the source?!

- Evolution

The TWA Source Code is the ultimate evolution of the iconic TubeScreamer; designed by none other than Susumu Tamura, the creator of the legendary TS808.

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.

Designed for players who worship at the altar of tone, Source Code builds upon the strengths of the classic “green box” while offering novel improvements that enhance the original circuit & expand its capabilities into new sonic realms.

- Key Features

Unlock new levels of clarity, headroom, and harmonic richness with the TWA Source Code.

Runs on a standard 9V power supply or 9V battery. The internal bipolar voltage regulator boosts operation to 18V delivering improved dynamics and massive headroom.

Multi-transistor input buffer preserves your guitar’s natural tone, while the exclusive “Magic ICOpAmp injects complex harmonics and an amp-like feel that responds to every nuance of your playing.

The all-new “BITE” control lets you alter the balance of odd and even-order harmonics: at higher settings, it shifts from symmetrical to asymmetrical clipping, emulating the saturation and feel of high-gain tube amps.

Built-in +6 dB boost gives your signal extra punch without coloring your tone, perfect for solos or pushing your amp into overdrive.

I bought these to provide a snug fit for an EV charging cable running through my garage wall. They worked perfectly to keep out drafts and crawly things. Highly recommended.

Worth the money!
Size: 50mm/2inch, Color: Black, Number of Items: 2
This kit is great. I bought this because I know that the seller paired the cutting tool to be the perfect size and it was! Not just that, but the hole cutter was well done and cut thru the 3 layers - laminate, plywood and particle board with ease. The only thing that I would do different, is go to 3" next time. 2" was very tight when running the 2 @ 120 volt cord ends through the cap.
