Seems like there's a lot of threads like this around, but I wanted to try and get a bit more specific with my bass distortion. The Rat and the Russian Big Muff seem to be the most common uses bass pedals to get some dirt on your tone. I want some distortion without losing low end. Also, keeping definition in my notes is key. I feel like with a fuzz pedal you don't get definition, but an overdrive pedal might not keep the low end! I play a jazz bass with a pick thru a Mesa 400+ head. Any suggestions would rule! Thanks!
