HAO Rust Driver

[indeedido]

I'm looking for a good overdrive pedal for some different tones with my JSX.

Anyone ever use the Rust Driver?

or Fulltone OCD?

Or the Toadworks Mr. Ed?

There aren't any around for me to try locally, but I can try out the rust driver from musicians friend and send back if I don't like it. I'm really curious too about the Mr Ed and OCD. Problem is I don't want to buy one and get stuck with it if I don't care for them. I know tone is subjective, just curious if anyone has used any of these.

I still like the good ol SansAmp if you are looking for variouse tones. I use a rackmounted PSA1.1. I bought it to use with my bass and vocals but the thing blew me away for guitar. In fact, I've been using it instead of a tube amp.
