In order to get the correct drum head size for your instrument, we recommend that you send us the drawing of your shell, this will ensure the best fit possible.
First step, is to remove the old head.
Next, draw the outline of the shell, please use cardboard for best results.
Finally, mail us your template along with your order #, this way we can provide you the best possible fit for your specific drum.
