Re: Cutting a hole in the bass drum...How big, methods etc...
I just put a kickport on my 22 inch Gretsch Renown bass drum. The reso head is a single ply Remo coated head and I csn tell you the difference is dramatic. I still bury the beater and have the batter head fairky loose to prevent the pedal from bouncing. I tightened the reso a little more than normal with the KickPort and it sounds great. Should have done a before and after sound byte. Kind of a tease right now with my healing elbow and not being able to spend much time drumming.

Feel. Control the Bounce.
