LMAO @ Jolly!
My band has played in standrd tunning since I joined. (well, half the songs are in standard and half are in drop D). So, in the quest to try to settle on one tunning, we tunned down a whole step just for kicks. I was actually impressed with the sound. We have a female singer, so I was kind of worried it might be a little too low for her, but it was perfect for her vocal range. I wouldn't say it made the band sound heavier, but maybe fuller/thicker sounding. And no, I don't scoop my mids. I keep them between 12 and 2 o'clock (but mainly depends on the amp I use).
