So I was at my P&W gig practice and they had a professional sound guy there to EQ all the channel's for a good mix. We just updated to a new mixer (high end digital) and they wanted to get everything sounding right. So he started with each and every drum, and then the set as a whole (spending almost a 1/2 hour getting everything right) then he moved on to bass, acoustic, keys, and vocals (spending a few minutes with each). Then he said: "okay now let me hear the electric lead" so I hit a chord, and after no more than one second he waved his arm for me to stop and said: "you're good to go, totally pro sounding, no adjustments necessary". Now that's my kind of guitar sound check
