FILTRON PRO WAH

This is a brand new 'Filtron Pro Wah' guitar pedal, designed and hand built by myself in England. It is a bandpass type filter with variable resonance (Peak) and has Envelope control mode, Amplitude triggered mode and Auto Wah mode. The modulation for the auto wah can be triangle wave, square wave, upward ramp, downward ramp and random steps. There is also a manual setting to allow the filter to be tuned by hand. Triangle wave modulation can be added to the envelope mode if required, or turned off by rotating the 'Rate' control fully counter clock wise.
