Tube Screamer TS808 Replica PCB: Ready-to-Solder Board

The ready-to-solder PCB for our Ibanez™ Tube Screamer™ replica (the ITS8), the mid-forward TS-808™ overdrive, with a layout that also builds several close relatives.

About the effect

The TS-808™ Tube Screamer™ is known for its smooth, mid-forward overdrive, and it is one of the most copied circuits around. Our ITS8 replica leaves out the original's FET switching circuit in favor of true bypass with an LED indicator; the switching has no effect on the sound. The layout was designed to take a number of variations and mods, including a 6-way clipping diode selector switch, a version with no clipper diode switch, and the AMZ Fat Bass mods linked on the project page.
