Re: Bass drum head help
Are you hearing that sound all the time, or just when you record? It is pretty common to get that sound if you are just sticking a mic inside the drum for the first time, so it could be a micing technique problem rather than a head problem. If that's the case, you'll need to adjust your mic position and/or put something like a piece of foam inside your bass drum to absorb those frequencies. It doesn't have to touch the heads, it's just there to adjust the acoustics inside the drum and avoid those weird reflected frequencies.
Let us know what pans out.
