Electro-Harmonix Tube Zipper Envelope Filter

The Tube Zipper sounds and intense as it looks and it certainly is a unique effect among the other overdrive/distortion and filter pedals out there. If you turn the sensitivity and resonance knobs down, it will act just like a regular distortion pedal. When you've dialed in some nice dirt, turn the resonance and sensitivity up and get some gnarly cocked wah sounds. This pedal has a bit of a cult following of some very dedicated and passionate users!

Very good condition, comes with power supply, no box
