Filter Effects(45 items found.)
Filter EffectsIn this group are two types of effects, equalizer and autowah / envelope filter pedals.
An equalizer is a more advanced sound control which allows single or multiple Frequency bands to be lifted or lowered, with a graphic equalizer the range in which adjustments can be made is set, in the case of a parametric equalizer these ranges can be defined individually by the user.
Autowah / envelope filter work in a similar principal as the Wah Wah pedal the difference being that the resonance peaks are controlled by how hard you strike your keys or pluck the instrument involved. With the Autowah the wahfilter is controlled by a speed adjustable LFO (Low Frequency Oscillator).
