Crying Time (LFO Wah) and Little Ducky (Envelope Filter)

Two mini filter pedals, built on perfboard.

The Little Ducky is Runoff Groove’s/Homewrecker’s Nurse Quacky, but with the attack control moved inside to a trim pot and a different transistor that I thought gave it a rounder “wauw” sound.

The Crying Time is a wah controlled by an LFO (like a tremolo), based on DeadAstronaut’s Lightwah. I simplified the audio path to make it more transparent. If you’re interested in building one of your own, you can check out the thread I put up on the Madbean pedals forum with the schematic and build document (in the Members’ Projects section.

Gear used:
Don Quixotecaster
Tone King Imperial
George L’s cables
Signal chain has an Orange Squeezer (my Clementine) that is off for most of the video.

  1. I really like the ramp switch.I’m going to use it on my build. It gives it
    a whole new depth. Good job

  2. Overall, I prefer the nurse quacky. I’ve also made the older BYOC, the one
    based on the DOD filter. However, the Mutron is just more powerful than
    both — if you need more than one filter sound, that’s the best. If you
    really just want a little bit of funk in your life, the nurse quacky is
    sufficient, even though it occasionally has problems with the high e & b in
    some builds. I think the Mutron can do almost all the craziness of the DOD.

  3. Maybe start a help thread on DIYStompboxes. It’s going to be too hard to
    debug it on YouTube comments.
