You might wanna try two of the Boss pedals. The black one gets a screamin distortion, but the orange one isnt as extreme. Also, if you have an amp with an extra speaker output (Some of the bigger Crates and Marshalls have them), you can plug some crappy little amp that has distortion into it, add any kind of distortion pedal and it'll sound pretty cool. I do that with the Crate GFX212 and a Squier amp.
