Anyone heared or tried it? Is it any good? its that little black cube thing you can wire directly in your guitar and is supose to some sort of overdrive sound.. i just remembered i saw this somewhere and im curious about this thing
Its basically just two diodes connected in parallel, with one reversed. You connect them across your pups output wires. Since it takes approximately 600mv's to turn on a diode, anything above that gets clipped. Try it yourself with two Radio Shack 50-cent diodes.
