The Ibanez Tube Screamer is the original warm, mid-range-forward, not-too-dirty, not-too-clean overdrive pedal. There are probably hundreds of other overdrive pedals out there that are either inspired by or are downright copies of the Tube Screamer.
This used Maxon era re-issue is in Very Good Condition - everything works/sounds as it should, just not in mint cosmetic condition.
Missing silver label from bottom of the pedal.
Can be powered by a 9 volt battery or 9 volt adapter (Not included)
