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?
