Classic American guitar distortion sounds from this pedal I've owned since the mid-80s, but which I haven't used since the early 90s.  It's been away in a box, which I just opened, and I've decided to move it on.  Great sound and all parts are there.  NO CORROSION IN THE BATTERY COMPARTMENT, EITHER.  It all works as it should, and will transmit sound from the guitar to the amplifier when on.  Features include:

-  Sound Level dial
-  Presence Level dial
-  Distortion Level dial
-  Line in/Line out
-  Adapter in, if desired (adapter not included)
-  Uses a single 9V battery

This pedal has been little used and is probably the most pristine of the 'used' ones around.  A couple of the pots scratch a little when turned, but that's easily remedied.  The pictures on this one tell the whole story.  Own a piece of American heavy metal (Distorted) history!
