![]() ![]() After having created a very good sounding wah effect by itself we added an envelope follower that will let you modulate the “wah” sound with attack and release set independently so you will be able to have a sort of “auto wah”. ![]() We faithfully recreated the sound of the pedal starting from the analysis of the circuit diagram, then simulated it and measured the response. Due to the simplistic design of the circuit the Q of the filter and its gain is not constant and both get gentler when the pedal is completely pressed down, also the filter resonance is obtained through a feedback in the simple transistor amplifier and creates different level of distortion at different filter frequencies, this gives the effect a distinct sound that can’t be achieved with modern designs (and in fact after many years this kind of wah effect is still one of the favorite of many musicians). The effect is created using a resonant band pass filter, the pedal changes the frequency of the resonance and creates the typical “wah” sound. This pedal represent a real signature sound for funky music and is an essential tool in every guitar player setup. The HoRNet WahWah is a digital replica of a vintage effect from the 70s made famous by guitarist and keyboard players around the world. ![]()
