Snow White Auto Wah
Another attempt at an auto wah envelope filter. I started with the schematic of the 7 of dwarves from Pedalparts.co.uk.
Overall the sound is pretty good, but given that I've just built an auto wah that sounds very similar (the Ducky von Quackenstein), I'm not going to bother moving this one to PCB for now.
There are options to change the sound by changing the filter capacitors, so I might get round to playing with that one day. The 7 of dwarves schematic was also a bit hard to read, and I later found easier schematics at Revolutiondeux and another at Madbeanpedals called the Auto Bahn, so I will possibly use them for a revisit.
