This is just a thought. But is there anything out there that lets you control which frequencies you put an effect on. Example is lets say for example u play a 7 string with low B. You want your distortion to be real heavy on the C and F strings but as light as possible on the B or E to not be distorted (or a light grit maybe). I guess it'd be difficult with all the overtones but it seems plausible to me. Never tried a guitar distortion but didn't know if those were set for specific frequencies etc etc. Most I can get is a decent distortion on low notes, but not a heavy distortion when playing high notes. anyone try this or know of a tool that would control a similar thing for other effects too?
