Re: Cutting a hole in the bass drum...How big, methods etc...
I cut a 4" hole in the resonant head of my bass drum for better recording sound. Used my 4" Paiste Accent Cymbal to draw a perfectly round circle on the head and then just cut it with scissors. Finally, I used a lighter to burn the edge to avoid tearing. It looks good and does its job just fine. Have never had any problems with it.
I chose to cut the 4" hole because I didn't want to change the sound and feel too much.
I'd say this method is a lot easier than the heated can method. Recommend it to anyone who doesn't want to pay for making the hole.
I know at least Gibraltar makes some products for cutting the hole and reinforcing it. Has anyone tried? I'm curious to know if they are any better than these free methods.
