Energise your sound with the Electro Harmonix Tube Zipper envelope filter and distortion pedal. Featuring a maze of vacuum tubes and an intricate set of filters, this distortion pedal uses a patented mechanism to enhance your guitar's signal with reliable analog harmonics. Use Tron or Trill mode alone, or overdrive any control to create a distinctive, custom tone.
- True bypass using a mechanical relay
- Overdrive stage allows interaction with the envelope follower for hard hitting sweeps and frequency color
- Tron mode allows the filter to sweep smoothly, following your amplitude's envelope
- Trill mode allows modulation to be added to the envelope as the filter sweeps
- Switchable up or down filter sweep directions
- Input gain boosts the signal before the filter drive
