The stock triple flanged hoops on a brass drum allows the drum to open up fully, but that brass"ring" is just a tad too prominent in the sound for me without any muffling, which I prefer not to use. The die cast hoops take a bit of the harshness of that ring out, leaving a really nice smooth tone. For me, I'd go with a gasket-less die cast hoop wearing brass drum. So to guess at your question, I'd say the BB without gaskets and with die cast hoops will sound sweeter than the COB with gaskets and flanged hoops. They'll be similar, but I think the gaskets will take away more of what you want in the drum than the triple flanged hoops will add. Make sense?I just ordered a 6.5x14 Supraphonic Chrome Over Brass. According to the stock photo, it should come with the gaskets. As far as looks go, I think the gaskets are a nice addition. I may think differently after the first time I play it.
I've been playing a b-stock Black Beauty without the gaskets. That drum has diecast hoops which I'm sure inhibit the sound of the drum a little. The new COB I'm getting will have triple flanged hoops which usually allow a drum to open up more. I'm wondering if the COB with gaskets and flanged hoops will sound similar to the BB without gaskets and with diecast hoops. Anyone care to guess?
