Electro-Harmonix Tube Zipper Tube Filter Envelope Filter / Distortion

Electro-Harmonix

Sold out.

 Unzip your soul! Just picture your guitar signal being massaged by a complex set of filters moving through a vacuum tube maze. Energized by two Electro-Harmonix 12AX7 tubes, the Tube Zipper's patented moving filter tastefully adds controlled analog harmonics to your signal. In typical EHX fashion, each control can be set over-the-edge, generating a host of novel tones. Tron or Trill a la mode!

FEATURES

  • 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
  • Resonance control adjusts the Q or peak of the filter ranging up to self-oscillation
  • Two Electro-Harmonix 12AX7 vacuum tubes included

  • "It's the most flexible little box yet." -- Adrian Belew
