I'm wondering how redundant the guitar's tone control knob is with the amp's EQ section. Most amps that I've seen have low, midrange and high EQ knobs whereas the single tone control on the guitar is more limited. Why then does the guitar have a tone control at all. Is there something you can do, or some way that you can impact the sound coming out of your amp by using the guitar's control knob that you can't do as well or better with the amps EQ section? Is it mostly because when playing live it's easier and quicker to do tone adjustments from your guitar?
