Stop banging your head against the drum, go get the Drum Dial, it also comes with a tuning chart for the top and bottm. That's by DrumDial Inc. Used by the pros. I preffer the Remo
weather beaters that don't go out of tune no matter what the ambience. If you can find them. Also the Remo
Pinstripe are good on my Gretsch
kit. Problem solved. Next?
