Mad Professor Sky Blue Overdrive

Mad Professor Sky Blue Overdrive

A hand built Overdrive from Mad Professor from Finland. Developed to give an already overdriven amplifier an extra edge. Or to give a clean amp a subtle edge overdrive with a nice long sustain. With the tone control (Texture) you can influence the grain of the saturation. And with the Z button you can adjust the impedance of the input so that you can make passive pickups a lot more lively, for example. You will also notice that the volume knob on the guitar will react differently to the playing.
