The line 6 Uber Metal pedal is supposed to be very good...I use an Ibanez Turbo Tube Screamer and I get plenty of dirt when I kick it in. I am currently looking at the VOX COOLTRON BULLDOG DISTORTION PEDAL AND THE RADIAL TONEBONE CLASSIC TRIMODE PEDAL but those are pretty expensive as pedals go. You'll want some kind of noise gate though (MXR Smart gate or Boss Noise reduction pedal)....There are alot of distortion pedals out there - no shortage of choices; you just have to pick what fits your needs and your budget b/c some are very pricey, but pricey does not always mean super thick distortion so do your homework.....
