What you need is the "Mudhoney" made by T-rex. Danish compakny. It is the best dist. pedal i´ve ever heard. It ranges from a gentle overdrive thing to that crazy sounding fuzz/stack tihing. Like your guitar it has a tone control, so that it ranges also from dark to bright. Check it out, it is the best! The bulesdriver would'nt be a bad choice either!
