Moo-Tron Auto Filter PCB

Excellent filter, and a great project to build

"I was interested to make this having previously made a couple of Meatball clones and wanting something smaller and simpler... the Mootron did not disappoint having similar great filter sounds yet far more easily tweaked from fewer controls. All the filters I have made all use VTL5C3s and they really are what's needed. This pedal sounds great on bass and guitar, and probably anything else. Well worth making." Jayjay - 14 August 2020

Excellent circuit, I recommend buying a Kit

"Mutron iii is the one. No one makes a close enough copy (that lovely liquidy recovery)and the difference is worth making one for. Not an instant gratification but once you've mastered the balances between, your guitar volume and the gain and volume on the pedal to surf the sweet spots, you have a full range of beautiful forward and reverse wah's that are as liquid and organic sounding as demos of the real unit ranging from the comfort zone of the traditional wah range to extreme mosquitos with all of the ranges set to high. I'd buy a kit if you can, the vactrols are becoming hard to find and unless you can find the exact pots and rotary switch you'll have the fun of four pots, two switches and a 15 lug rotary switch to offboard wire which is no kind of fun."
