From the post
Here is a "heavily modified" layout for the old and weird Funny Cat.
The original pedal sounded a bit...
Me and Gavin (Hozy31) have been working on this to try to improve the sound.
We added Moosapotamus mods, a buffer at the "Normal" side input to avoid "tone sucking" problems and a boost (SHO) at the SDS/Normal switch output that works only when the Harmonic Mover is switched off, to avoid volume loss when using the fuzz on its own.
Gavin has tested the final result and he's very happy with it.
There are videos of the original AG-5 on YouTube but we prefer not to add any here cause this version sounds quite different (in a good way)
You can find more infos and sound clips of Moosapotamus modded version on his website here.
