Looking for Morley Distortion-One/Power Fuzz Wah mods.

[Hobbit]

I'm specifically looking to add Q control for my Power Fuzz Wah, the subharmonics are great but the high end has such a short gate before it tries to blow my speaker.  I just want a way to even things out, you hear nothing but a rumble then suddenly it's screaming.  It's a Cliff Burton tribute pedal and, I think he would be rather disappointed with the sound.  If anyone knows of anything fun to do with the Distortion-One let me know, the Power Fuzz has the same exact circuit with a small mod for adding more mid for a bass.  Since it's a redundant pedal I figure why not make it do something strange or a little more unique.
