ProCo RAT2 Serial: RT-212781 (1990s) Made in U.S.A. Includes the pedal, box (white box with red text), and a power adapter. *No instruction manual* Functionality confirmed. No scratchiness, and the switch works perfectly. The exterior is in good condition considering its age. I purchased this used this year and used it twice on stage. I'm selling it to downsize my pedalboard. The LM308N op-amp can be seen on the circuit board (see photo). It produces a thick, sticky RAT-like distortion. Please note that this is a used item, so no returns or exchanges are accepted.
