So if "projection" and volume are the same thing...........
I was just reading this thread about Mahogany snares - and several testified that the bigger factor in the volume of the drum was the edges (NOT the soft mahogany wood)............http://www.vintagedrumforum.com/showthread.php?p=317458#post317458
so...........doesn't this trump the common belief that the mahogany shells are the culprit making these lack volume? ....and perhaps it's the EGDES more so than the specie of wood.
BTW - I am NOT advocating the re-cutting of MIJ toms. Instead, if you are in a live situation that has no micing and you need to cut through a bunch of other instruments - don't use your vintage MIJ then. But really, if you have the benefit of mics, use these vintage MIJs and just let the sound system do your heavy lifting. Deliver the raw goods though - some nice vintage tone.
For the record, I have NEVER applied anything to the interiors of any of my vintage MIJs. Meanwhile, I have NEVER had anybody complain that my toms were not loud enough. Am I that much of a loud beast? (I use 5As)
