EHX Tube Zipper


Add to Cart
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! - 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
