Or your money back, no questions asked.
EXchanger Pro
A low-noise electronic equalizer that expands the bandwidth of your microphones and creates new sonic characteristics. Activate it and choose from 8 customizable voicings; deactivate it to return to your original sound.
Change of wah,
without changing the wah.
Plug your own wah pedal into the Wahouwah: a true wahs workshop, patented and 100% analog. Compose, save, recall — and produce much more than a wah.
Wow!
Plug in your clean wah pedal — and/or an expression pedal — in the Wahouwah and access unparalleled playing expressiveness. Thanks to our patented wah detection system, you unlock all the wah sounds, without changing wah pedals.
Everything is analog, except for the setup: a complete mobile app (iOS/Android) makes it a wahs workshop — Default library, personal library, storable presets. And well beyond wah: violining, volume, boost and automatic effects.
Pure analog, patented
Where everyone else is digitizing, Keyztone remains 100% analog. Our low-noise equalization circuits capture and balance all the guitar's vibrations to recreate entirely new pickup characters — no latency, no conversion, no loss.
It is this approach, protected by our patents, that makes the EXchanger and the Wahouwah literally unique on the market.
Understanding technologyAdopted by those who seek sound
«"This pedal breathes new life into some guitars and transforms others. The output sound is excellent, and the value for money is exceptional."»
«"My Charvel transforms into a thick Gibson, then into a snappy Fender. You can even get some jazz tones out of it. Killer."»
«Opens up a nearly infinite palette of possibilities. The only boutique pedal I've bought in a while, and I don't regret it one second. »
