I use pedals to get really nice overdriven tones from them. I tend to play more in the classic rock area, but if you take something like Alex Haervey's Midnight Moses, with one of JuanSolo's modded muff pedals, I can get all the drive I need to capture the sound. Another one I play, where I really like the sound from them is Comfortably Numb, where they can nail all the tones from the live version, again using pedals to bring in the gain.
