Xox Audio Tools Eleven Electrix Human Sensor Wah

Eleven Electrix is ​​a trademark of XoX Audio Tools. Eleven Electrix offers pedals handmade in Italy.
This model wah is brand new and barely raises the foot (the foot end) in France when I post this review.
I found this model by directly contacting the manufacturer in Italy. He told me the only shop with some French models (a famous Parisian boutique near Bastille, whose initials are PB). No sooner said than done, I jump on one of two models in the shop.
Here's the scoop:

- Fully analog
- No tipping!
- Switch from mechanical activation
- Vintage patterns (400-2200 Hz) and modern (300-2500 Hz)
- Potentiometer sensor sensitivity and progressiveness
- True bypass
- 9V battery power or mains (adapter included, which is rare)

Technology? Eleven Electronix do not reveal. Personally I look for a sensor type ® Theremin, as used by Zvex Probe on its range. For the rest, Eleven Electronix uses field effect transistors (FET), whose operation is more progressive than that of conventional transistors (lamps even close).

Quality of workmanship and remarkable construction. Superb presentation.

UTILIZATION

Okay, so you understand: no tipping. A sensor "captures" the position of the foot or hand, or what you want, and controls the scanning frequency.
In short, the use is tantamount to wah-wah into space on a virtual switch. Advantages:
- No mechanical parts: no wear, no noise
- No switches to operate: it is possible to adjust the wah effect with great precision and speed
The sensor is accurate, sensitive and progressive when scanning.

In fact the difficulty is to properly calibrate the sensor. Two knobs to adjust the sensitivity of the sensor and the progressive scan. But what makes calibration difficult is that these two knobs interact with each other. For a low sensitivity of the sensor, it takes a quick scan. For a high sensitivity of the sensor must instead a very progressive scan. Writ not simple, especially since the adjustment is made using 2 different screwdrivers with knobs arranged on the right side of the pedal.

on the other hand, once calibrated, this pedal and its virtual flip is ruthlessly efficient: The accuracy and sensitivity!
In addition, the sensor "lights" in red As the scan (as in the diode Probe Zvex elsewhere). Besides being convenient, it's beautiful!

SOUND QUALITY

At the sound quality! A marvel, both for the user "vintage" as the "modern".
The vintage fashion is soft and warm, perfect for blues.
The modern fashion large distortions cash quietly keeping a nice presence.

A real success.

OVERALL OPINION

This is a great pedal that houses the latest technology and offers a nice range of sounds.
The secret principle of the sensor is based on my opinion on a Theremin ® similar to that used by Zvex. Now I could be wrong, but the mode of operation is still very close and reminded me of my home Probe Zvex.

The price? 270 euros. It's worth it.
