Adding a three band EQ to a Muff or Devi Ever Hyperion

[matmosphere]

has anybody tried this? Might make for a fun project. I figure in the Muff it would fall in right where the tone circuit is, but I started to think it might work better in front. I figure if it replaced the tone control the last gain stage would need some modding.

The Hyperion might be fun to mess with.
