Versatile, intuitive, and unique, there’s nothing quite like it. The original PDF-1 put Stone Deaf on the map, evolving the legendary Maestro MPF-1 and dragging it into the 21st century. The PDF-2 turns things up a notch, bringing more gain and more flexibility for the ultimate overdrive and distortion effect.
