Spruce, yes you are. But you're not the first. I've been getting suggestions of all types (some nice, some not) on the AG forum.
The key differnce between last week & this week will be the use of test tones, probably 250Hz, 1kHz & 5kHz. I know I have those downloaded and functioning on my iPod. I also have pink noise. I think I'll use that too, although I'm not sure what it'll mean. (Pink noise is supposed to contain "all" frequencies.) We will calibrate the amps this time for the same starting sound level. I'm told that it's not necessary, that the change in db's is what really matters, but it'll still be easier for most of us to compare if we pick the same starting point. And we will make sure we have the sound level meter in the same exact spot for comparison tests. Last week I used a mic stand as a tripod. That gave us some consistency. But I didn't mark off the spots I was measuring from & then tried to get the mic stand back to the same general area on the next amp. I have to look to see how many mic stands I have at home. If I have enough, we'll set up the mic stands and then move the db meter from one to the next. If not, I'll be marking the measuring spots with duct tape so I can find it again.

Just want to make sure I clearly state how much I personally appreciate the efforts and that I have no problem whatsoever of the exactness of any of this. You guys sure sound like you're doing better than I ever would so be sure that there is NO criticism from this peanut gallery.

I don't think I'd want to do this for a living, but it's been kind of interesting so far. Basically, we're trying to figure out how to come up with a meaningful way to compare the amps, something more than just "My amp is better than yours."
Some people have gotten really worked up about the way we're doing this, implying that we're amateurs. And we are. --------------- I don't think I posted it here, but last summer on another forum, a guy was getting ready to travel across country with his guitar in his trunk. A lot of people, including me, told him not to do it, that he should keep his guitar in the passenger cabin. He said that he was going to have five people in the car and HAD to keep his guitar in the trunk. I tried to talk him into putting at least one of the passengers in the trunk. (Guitar first, right?) But then a couple of us, me and another guy from Minnesota, started wondering just how hot a trunk gets in the summertime. I have since switched to carbon guitars and have no need for them anymore, but I used to have several thermometer/hygrometers with remote reading capability. The guy in Minnesota ran his own tests using his own methods. I ran my tests using my own methods. We both came to the same conclusion: because of the greenhouse effect with a car sitting (parked) in direct sunlight, a car's trunk will stay about 20% cooler than the interior of the car's cabin. You should have seen the grief we caught over that one.

First, thanks for taking the time. I can't say that I've tried every one of your suggestions, but I've tried most, that is how I ended up buying the Platinum EQ. As far as the room is concerned, yeah I do have glass doors, but I open them when playing and the sound projects out into a larger "great room". And I've tried to "tame" the room(s) by buying black out curtains, which my wife sewed together, and I modified a couple of speaker stands with pvc to mount the curtains as a back drop. The idea was to put something behind me to reduce the refracted sound from getting back into the mic. I take the curtains if I'm playing a venue I know that will have a hard wall or glass behind me. My observation has been that it has helped when playing "out" in the larger venues but does not seem to help at home. Having said this, I am going to go back and try your suggestions, as I doubt that I was as precise as you're suggesting relative to clip levels. And who knows, it might work! Again thanks!
