From the vendor
The best Colorsound Overdriver PCB with the most popular mods!
Description
The classic Colorsound Overdriver bridged the gap between Boost & Overdrive recreating many of those popular, but hard to get tones of the 70’s. A favorite of Mr. Gilmour and Jan Akkerman of Focus among many. Now you can build a similar circuit. We have added some modifications to the original by adding a Master volume control and a simple mod to smooth out the Gain Control mapping.
Must have for vintage tones!
