Keeley Fuzz Head ...

I had been looking for a fuzz to put on my board. I found a Fuzz Head and it appears to work very well for me so far. I needed to increase the gain a touch, but otherwise no other changes. A search turned up a few users here. There are a lot of ways to use one of these pedals.

For you users, how are using it,what is your rig and what settings are you using on it? So far I have been using mine full on, with an LP or Tele but back down on the guitar volume. I tend to generally use the Ger fuzz side and not so much the SI OD boosted side so far. I do hit it with a TS or DS at times though. I love the early ZZ tone I get from this pedal.

Any singing sustaining lead settings that are favorites.
