Remember that what anyone says about drums .. High pitch tone outside the bearing edge or drums that are wrapped in a finish changing the sound doesn’t mean that these things are bad they may very well add character to the instrument that you love
That sir is the best explanation of bearing edge I've ever heard, thank you. I've been wondering why modern drums don't sound much like the 70's and earlier drums. The newer drums have to many weird overtones and no internal mufflers to control sustain.
I build drums as well i particularly like the double 45 with the apex dead center of the plies like a pencil tip. This edge gives me the most attack and since the apex of the edge sits away from the elbow and under the flat part of the head of the head much like an undersize premier drums shell I get a very resonate and clear tone. I like round overs for achieving a vintage tone but for fast aggressive music like punk or metal the double 45 is where it’s at. I borrowed this edge design from Spaun Custom Drums and have seen it often on SJC and Dark Horse drums. As a punk drummer the sharp double 45 is the best!
