Tube Zipper The Tube Zipper is brand new from EHX and is actually two pedals in one. It combines a tube distortion unit (which uses top of the line 12AX7's) with an envelope follower. Together, they create some wild new effects. The Drive and Input Gain knobs are for the distortion, the rest of the controls let you tweak the filter.
The Mode switch is labelled "Tron" (for a smooth filter sweep) and "Trill" (modulation added to the filter). The Env switch is labelled "Up / Down" and selects the direction of the filter sweep.
