The Micro Q-Tron Envelope Filter Pedal from Electro-Harmonix is an envelope controlled filter pedal which is a unique type of sound modifier in which the user's playing style controls the effect. The volume or the envelope of the input signal controls the cutoff frequency or center frequency of a swept filter. As your instrument's volume increases or decreases, so does the pitch of the filter.
Drive control sets sensitivity and filter sweep range
Selectable low pass, band pass, or high pass filters
Q control sets the filter's bandwidth from smooth to funky
