I'm selling this as I bought it as a spare but have no plans to use it. I have not opened it beyond what is shown in the images. *The top image is a sample. The first modern overdrive pedal made by a guitar player for guitar players. With this pedal, you no longer have to struggle with your tone and equipment. The Precision Drive works with any setup, both tube and digital, and with precise tone adjustment controls, you can transform it into the perfect modern metal rig.
