This is a Dunlop TS-1 Stereo Tremolo pedal. As the name suggests, this pedal gives you a variable tremolo effect in either stereo or mono, all packed in a solid metal package. This piece has some bumps and nicks from a life of gigging, but it functions normally and sounds great! There is also some adhesive residue on the bottom of the pedal, presumably from velcro strips.
