I'm getting ready to go into the studio and record on a semi-metal/prog rock CD and the band leader wants my tone to be a little meaner/more aggressive on the recordings. I'm so used to having a clean tone for everything else I play outside of this project but this is a new area for me so I'm looking for examples of tones I like. I'm liking Liam Wilson's tone on some of Dillinger Escape Plan's newer stuff as well as this chick's tone in the Pink Panda. (Japanese pop punk) I'm clueless when it comes to distortion or overdrive pedals for bass. Enlighten me please.
