Electro-Harmonix Big Box Q-Tron Envelope Filter Guitar Pedal (Pre-owned)

This is a vintage (circa 1990s/early 2000s) envelope filter pedal that Electro-Harmonix call "a very powerful tool for musical expression....Envelope controlled filters are a unique type of sound modifier where the intensity of the effect is controlled by the user’s playing dynamics". Functions include: Drive Switch, Range Switch, Gain Control, Boost Switch, Peak Control, Mode Switch, Bypass Switch. The appearance is in keeping with its age and use, and it's in great working condition. The power supply is included, but there is no box.
