Add some funk to your pedal board…and a fixed wah too! The BYOC Envelope Filter & Fixed Wah has 3 parameters when in envelope filter mode: Sensitivity, Range, and Attack. When in fixed wah mode, the manual knob lets you control where you park the frequency, and the range knob lets you control the Q.

This circuit uses a 13600 Dual Transconductance Operation Amplifier and has a fairly low part count, making it a fantastic sounding envelope filter that’s very versitile and easy to build.
