Here for sale I guarantee you will never see another one like it out there! An all original 1979 proco rat with the exceedingly rare tone knob. This pedal has been locked away in a closet from 1979 when it was purchased until being taken out just to be put on the market. The condition is absolutely astonishing! Almost not a scratch on it. Looks better than some "new' stuff out there. Everything works as you would expect it to from buying it brand new at a store yesterday. Except that yesterday was over 40 years ago! The sound will absolutely blow you away! Worth every penny I'm asking for it. You will never see another one like it out there!
