I had a thought the other night (a rare event, and one that occasionally results in shrapnel wounds). In our modest PA we've got this Behringer graphic EQ that has a built-in real-time-analyzer and pink noise generator. It's very handy... we just place the reference mic out in the room, punch one button and the EQ automatically compensates for room acoustics. Neat. You can set it to match a sound you know you like, or you can set it to try to get as close to flat as possible. So, just out of morbid curiosity, I was thinking of plugging the sucker into my bass cab to see what it comes up with if I ask it for "flat" response. Naturally I'd ignore all the higher frequencies... but presumably this exercise would give me a realistic baseline EQ to play with, rather than assuming that setting all the knobs at 12 o'clock will give me flat response. See, I KNOW that cabinets color the tone (plug a different cabinet into your amp with everything set to "flat" and the sound changes, right?). The same goes for room acoustics. So therefore I KNOW I've never actually heard what "flat" is. I'm reasonably sure that I won't like it, but it would be nice to find out. Am I nuts? I'm going to try it anyway since I can't hurt anything, but I was just wondering what you all thought of the idea.
