I've been thinking about replacing the stock bridge pup in my Agile with a ceramic Warpig. I have the 7 string version in a cheap Schecter with a basswood body. I really like the tone, but the guitar can't stay in tune, so I basically use it for tone tests.
As for the Warpig being muddy, I thought so too when I heard the clips people were posting of them on the BKP forums, but my personal experience with them has proven otherwise. Was also thinking about the Cold Sweat as well.
