I use clones, and deviations of the pedal. BBE Green Screamer, Boss SD-1 (modded), Wampler Pinnacle 2 and a few others.
I'm not really a fan. I get better results with my Joyo OCD clone, and my Doomidrive. I'll probably get a Ubangi Stomp at some point. I want grind when I dig in, but sparly cleans when I pick lightly.
I get the best results with my Billy Brain, and a clean boost. Nice crunchy overdrive.
The love of money is the root of all evil.....damn, I could use some really rather naughty right now.....
