OK, so being a producer I commonly use multi-band compression on complete tracks to help pull together individual sounds into something that sounds like a single unit. Multi-band compression can add 'punch' and 'warmth' while not affecting dynamics of the mix as a whole. So here's my idea. What if someone desinged a processor for multi-band eq-ing. In other words, lets say one 15 band eq for each of three frequency ranges. This processor would detect the fundamental note, ignore the overtones and harmonics, and apply whatever eq settings were appropriate for the frequency range of the fundamental. Something like this could allow you to apply different eq settings to different frequency ranges on your neck, so for example, a low pass (high shelving) on lower frequencies for warm, dark sounds while playing backing rhythms, but at the same time allow bright sounds through when playing on the D & G strings. Thoughts?
