Tube Zipper

Envelope Filter/Distortion
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!

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

“This Disaster” - New VideoSong by Jack Conte
Posted 5/6/2009
Cheers to Jack Conte for "This Disaster," his latest 'videosong' -- I spotted a HOG, a Big Muff Pi, and a Tube Zipper (and for EHX shirts, check out the merch shop).

btw, Jack's videosong rules are: 1. What you see is what you hear (no lip-syncing for instruments or voice). 2. If you hear it, at some point you see it (no hidden sounds).

EHX Strings
We've been playing these EHX Strings ever since we first took them home to try them out, back in 2002.

We find them to consistently offer rich harmonics with powerful definition, while also lasting longer and staying in tune longer than conventional strings.

We use them, we like them, and we think you will too. Available in 9's, 10's, 11's.
