You will find what FDR said is a good rule of thumb on strikers.
I personally have found the for any unknown reason, some calls just "prefer" a different type of wood. For instance....I made a run of slate over glass pots out of cedar. 4 of them sounded perfect with purple heart strikers.....one of them sounded like squeaky trash.....until I tried a Maple striker.....now it is in my own turkey vest it sounds so good,
Play around!!!!
Every callmaker and every turkey hunter has a different "ear". I have been at shows and have a guy pick up a call, play it, shake his head and walk away, only to have the next guy who picks it up to play it claim it to have the best sound hes ever heard and whip out his wallet.....LOL.....
My favorites
Cedar.....slate over glass.....purpleheart striker.......low raspy hen sound
Maple......slate over glass......walnut striker........Beautiful clear tones....
Padouk.....slate over glass......whatever striker makes it work......This wood make the loudest pot calls over ever made. Dont know why.....Must be the physical/acoustic properties of the wood
