ITALIAN WAH - Deep Analysis

Product analysis

The Italian Wah is the result of three years of design and develp, to produce a worthy heir of the wah wah produced at the turn of the 60s and 70s who created the myth of Italian wah. We developed our halo inductor and we set the circuit for a very gently sweep usable in the whole range of the rocker.

The most important component of the project is the inductor, which was developed and tested in almost ten variants before deciding the most suitable for the Italian Wah.

We have chosen for a HALO for the possibility to wrap this specific component in the laboratory and to guarantee a constant quality. After winding, the coil is impregnated to minimize the microphone effect. A second impregnation takes place after the assembly and the test process.

The Italian wah is designed for be full tunable by the user, acting on a couple of trimmers and 4 dip switch is possible to deeply modify the dynamic and frequencies response of the wah-wah.
The FOCUS trimmer modifies the gain and add beefy low end. The MID Switch change the Q of the filter for a bit modern and resonance response. The OUTPUT Trim acts gain of the output drive for vary the overall level from 0dB to +4dB. The output driver is custom designed for be able to drive correctly a germanium fuzz pedal after the wah.

Let's check how the frequencies response may vary at the different settings. The BOLD line is the TOE response, the THIN line is the HEEL response. For all the settings the FOCUS was at the min and MID off.
