Recently I've been getting into the percussive style of guitar playing, but instead of using a microphone live (which can be hard to keep in mind while slapping around) I want to put a pickup system into my guitar that will capture the tones of the body.

Two of the systems i'm looking at are the...
K&K Pure Mini
and the
LR Baggs M1-Active

Does anyone have any experience with these pickups or recommend anything in particular?
