Interestingly I did a recording comparison (Accept Balls to the Wall and just using bridge pickup) and the EXA-1 kit sounded best to my ears, then the Greco then the Gibson. They all sounded great and very close, but the EXA-1 had the edge for me.
EXA-1 has Seymour Duncan Custom TB-5. Gibson has 500T and Greco has Maxon U2000 (I think).
