Hi there,
Listening to a 26", 12", 13", 14", 16", 14x7" Rolling Bomber kit, I really liked the bass drum, snare and 12" tom, but the 3 remaining toms were lacking lower harmonics to my taste.
Looking into the shells, I noticed that the 12" is the only one without a center wooden reinforcement ring. I know I'll probably get flamed right away by all those who believe that such an instrument should remain as close to its original state as possible BUT I want it to give its fullest sound both on stage and in the studio.
So... my understanding is that the more a shell is flexible (especially in its central section), the more the deeper harmonics can develop. In the case of this kit, the central reinforcement rings were probably installed to help with the tom mounts etc. but I'm pretty sure they don't do any good to the sound.
In short: what would it take to remove them?
Not sure if un-glue-ing is really feasible without harming the shell.
Any thoughts apart from "burn this heretic?" ;-)
