IBANEZ™ TUBE SCREAMER™ (TS-808™) REPLICA COMPLETE KIT WITH DIODE SELECTOR OPTION

A complete kit to build the ITS8, a replica of the Ibanez™ Tube Screamer™ TS-808™, with a 6-way diode clipper selector so you can pick from six different clipping sounds.

About the effect

The TS-808™ is the most famous overdrive of all time, known for its smooth, mid-forward drive that pushes a tube amp nicely. The ITS8 replica leaves out the original's FET switching circuit and uses a true bypass switch with an LED indicator instead, which doesn't affect the tone. The board supports several variations and mods, and the project page also includes layouts for building a Boss™ SD-1™ and an MXR™ ZW-44™ on the same PCB.

This kit adds a 6-way diode clipper selector switch, and the 125B enclosure is pre-drilled for it. Photos include this kit in the Twisted Screamer casing (see Related Products).
