We took a classic distortion circuit and hot-rodded it to the next level for over-the-top soaring leads and rich, saturated rhythms. With only three knobs, dialing in Badass tone is a cinch. The CRUNCH button allows you to choose between two different modes of diode and LED clipping, boosting the harmonic content of the distortion.
The '78 Distortion's wide open amp-like sound sounds great whether it's in front of a clean amp, a slightly dirty amp, or a full on overdriven amp. Under the hood, this high performance machine features top notch circuitry and hardware meant for a lifetime of use.
Some of the cap values may seem a bit off. These are the measured values of the SMD components on the actual board. So i suggest you try on the values that are closest to the ones measured. Same thing with semiconductors.
Now this layout is also verified, thanks to Csaba and John for their footwork.
