Hey guys, thinking about getting a new overdrive. My brother just got a Blues Driver for his guitar the other day and I decided to try it on my bass. It sounds great....warm, crunchy overdrive; i like its tone quite a bit better than my ODB-3. Thing is, even when the tone knob is all the way to the left, I'm still not getting enough bass. I know Keeley mods them, and he claims they're good for bass. I wasn't really sure how good the bass comes through after the mod. On the other hand, I can, for slightly more, get an English Muff'n. I love my Big Muff Pi fuzz, nice and warm, and was wondering if the Muff'n was just as good for an OD. I know it has a three band EQ, so I suppose it would be alot easier to keep the bass on it. Which one would you guys recommend? Also, even though I usually play slap bass straight, and slap is not usually considered super when on a tube amp (and therefore probably not the best with a tube/tube emulated OD), which pedal would slap sound better on? Hope you guys can help.
