Aloha,
The Magmic works very well in percussive styles. The mic can be blended to taste - no issue. Although I don't have any clips to share, you can clearly hear the Magmic in that style on several samples available at Doug Young's pickup comparison site here:

Doug has several samples of the Magmic in the higher-numbered samples above #71.
I must say that the Mi-Si Duo also works great in tapping styles too.
