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.
