I thought I wanted a wah, and it turns out that I'm really uncoordinated and can't manage my hands and feet at the same time. It works great, fits perfectly on pedal boards, and it sounds pretty good with the three range options. I took the rubber feet off of the pedal, but they're in the box if you want to use them.

AMT WH-1 is an optical version of a classic “WAH-WAH” effect with bandpass filter range selection (3-way switch). Optical frequency control increases the service life of the effect eliminating frequent replacements of maintenance and replacement of the control potentiometer.

AMT WH-1 features low noise and expanded frequency tuning range due to the use of original JFET-based circuit design. AMT WH-1 boasts great versatile sound and processes both clean guitar sound and Ultra high gain overdrive equally well. AMT WH-1 features:

– Removable support feet (the option is useful when you install the AMT WH-1 on the pedal board);
– Effect monitoring by using blue LEDs on both pedal sides (visible engaged AMT WH-1 mode);
– AMT WH-1’s steel heavy body is stable and confidently responds to foot control;
– Adjustable pedal movement by means of an axial screw;
