I would definitely agree that OLP MM guitars are the best value in the $500 or less category.
The PRS SE may be the best guitar at that price range that I've ever played. They are scary nice! I don't get goo caught up in what price range OLP's really compete. Would say that generally they are an amazing value for the price I've seen them selling for in stores though.
And since they received approval from and were licensed by Ernie Ball/Music Man, I would consider them to be a part of the EBMM family of instruments in that sense.
