Purely for chauvinistic reasons: Big John effects.

Hairy Balls: big fat wet fuzz, massive lowend, very good note definition, gate control is very usefull when playing very fast (which is a big plus for me)
... I AM the brass section with this one.
Grannypuker: fuzz + octaver, more harsher and synthier in tone, sharper fuzz
one bad point: some time to learn the controls, they are not that linear and volume rises and drops when tweaking settings... just something you have to overcome.
I am auditioning the Hairy Balls among other dirt pedals to see which one will get the place on my pedalboard. (I'm testing out a lot of different types of dirt to see what I can use the most... overdrives, fuzzes, distortions, dirty octavers,...
Grannypuker has found its way onto my guitar pedalboard. Awesome guitardistortion... VERY IMPRESSIVE. (Also awesome on bass but not what I'm going for currently in my band situation)
