The ProCo RAT 2 with Motorola LM308N chip has been produced in the 90s.
The pedal offered here is a very early Rat2 (from the transition period between the small box “the Rat” and the Rat 2).
This becomes clear by looking at the riveted battery compartment and the metal-screw.
The Rat is still the reference for distortion sounds.
The list of famous users is almost endless.
In contrast to the recent reissue pedals, the early models like this one provide a more open sound.
The pedal is technically and optically in perfect condition.
