From the vendor
A simple OD, the original had just one control, a bias knob – we’ve added to this with a master volume and a clipping diode toggle. A easy to build circuit that will give you clean boost to a light overdrive, which can really push your amp.
Controls
• Gain
• Volume
• Clipping (toggle)
