A few questions for Aron (Aron ... is that the correct spelling?) about the test.
Was the action set up done by measurements and done exactly the same on both necks?
Same for neck relief? Exactly the same by measurement?
Are you absolutely sure the mic position was never changed or even touched by a human since initial setup and was exactly in the same position for both recordings?
Same for the amp settings ... never changed for both recordings?
I assume it was a tube amp?
So... was the room temperature the same for both recordings and the warm up time for the amp the same for both?
Also, nothing new added to the physical environment near the mic in front of the amp like a chair or stool or brief case
set down close to that area?
Thanks!
I'll answer all these questions as accurately, and with as much humor, as I can.
The correct spelling of my name is "Aaron". Thanks for asking! I need a reminder sometimes too. I chose the username Double A for just such emergencies.
I don't know if the action was adjusted by measurement. I didn't do it, and wasn't there when it was done. The guitars were given to me ready to go, and I played them. I can tell you that they were set up very similarly....it's not like they were wildly different. One variable that I should have measured was the distance between the strings and the pole pieces on the pickups. That may have varied slightly, or it may have been exactly the same. At this point I have no way of knowing. But, that ship has sailed. Again....the action and setup on both necks was very similar, and given the fact that the necks were identical in all respects, I would guess that any difference in the distance between strings and pole pieces was insignificantly small.
As far as amp settings and mic placement, this part I did have control of, and yes: I am absolutely certain that neither the amp setting nor the mic placement were changed between recordings by human hands. Or the hands of any other species with hands. Or the hoofs (cloven or otherwise) of any other animal. Or paws. Or flippers. Nothing was bumped by a badger, changed by a chameleon, or turned by a tortoise. Also, no rocks or other minerals tumbled into the mic stand.
The amp was a Fender Hot Rod Deluxe....a tube amp, and one of the most common backline amps around.
I did not take a temperature reading on each day, prior to shooting. I also did not bother to record the humidity lever, barometric pressure, or wind speed and direction. The room was approximately the same temperature both days, a comfortable 70-ish degrees. We use forced air heating in the office here at Warmoth, and we shot the video in November, so the humidity level was probably a bit low. Sunrise would have been slightly earlier on the first day, and sunset slightly later. There was a waxing gibbous moon on the first day of shooting. Full moon on the second. Waning gibbous on the third, but no part of the test was shot that day....just my summation. A quick check of the Pacific Northwest Seismic Network website shows there were five minor earthquakes in the area on the first day, the largest/closest of which was a 1.1 magnitude, centered in Morton, WA, about 53 miles away. However, on the day of the second test there were fifteen, the closest of which was a 2.4 centered about North Bend, about 40 miles away.
The amp was fully warmed up for both recording sessions. It sat at idle for a similar amount of time on both days - at least a half-hour before recording. Actual recording time was a little longer the first day, as I had to "write" the parts for each test, and then notate their tempos and pickup positions as I went along, so I could duplicate them for neck #2. Shooting the second day went quicker. I refreshed my memory of what I had played by watching the first day's clips, and then just went in and played straight through them.
The environment around the amp and mic did not change at all between days. To my knowledge, nobody at Warmoth even owns a briefcase. Or a business suit, for that matter. A fern did not grow in front of the speaker. Some plants in the office would be nice though....it would make it a lot more homey.
