Jim, thanks for the input. One thing I've found in my little experiment is that tuning is still a thing - I had to carefully retune each tom after taking off the bottom heads. Now, in a sense, it's easier because there is only one head to mess with, but it's a whole different kettle o' fish, and it's easy to make that one head sound bad. My tinkering shows "boingy" and "overtones" means you're in the high-middle range. Going higher cleans up the sound a lot, but is pretty specialized. Going lower gives a deep punchy tone free from weird overtones. I have experimented a bit with EC2s, clear Ambassadors, and moongels, and I can now get a usable sound with any combination. I am frankly surprised at how similar the different heads sound when tuned just right. Even the clear Ambassador doesn't require dampening unless you just want it.Hey headless tom lovers.
Last night at my open jam I tried removing the reso head on one of my toms. I removed the reso on my 12" tom and left the reso on my 13" tom. The 12" had a slight boing' sound. Some weird overtone. It was not louder than it was with the reso head. And it did not sound as full and resonant as it did with the reso head. My conclusion is, if the tom heads are tuned correctly the tom will be louder and sound better with both heads.
I can't speak to "louder." They just sound different. And as an interesting side note, my Mrs, who usually has no strong opinion on drum sounds, said she REALLY likes the sound of the concert toms...
Weird, eh? lol
