Capturing a Legend's Sound - Cloning the Cornerstone Gladio SC

Stevie Ray Vaughan was one of the greatest rock / blues guitarists of all time. Many people have attempted to capture his distinctive tone, and many pedals have tried to capture that tone as well. The Cornerstone Gladio SC standalone preamp takes a somewhat unique approach by allowing a blend of the clean and driven signals - along with volume and tone control. There is even a toggle that allows for compression to be added to a signal. The end effect is you can essentially get a tone which sounds like it is running through a dual amplifier set up with one clean amp and one overdriven amp. I had a request to build one, so I went in search of a PCB and got to it!
