Re: Tonal Characteristics... LP vs ES-137
I have an ES-137 Classic with a set of Seth Lovers and a LP Classic with a set of Antiquity HBs that I installed on Saturday. They both sound great. The Gibson claim that the ES-137 sounds like a LP is maybe half right. I think the bridge pickup tone is very LP-ish, maybe a bit thicker as if it was a LP with a slightly overwound bridge HB. The neck tone is quite different -- not as much chunk, thunk, and punch as a LP neck HB tone -- definitely a semi-hollowbody neck tone. The combined tone is also more semi-hollow/ES-335 sounding than LP.
I would say that my LP Classic is much brighter than my ES-137 Classic, which has a mellower tone. My LP Studio with stock HBs falls somewhere in between the two.
The upper fret access on the ES-137 is pretty limited, even compared to a LP, so you might want to consider whether that would be an issue (it's not a big issue for me). I also have to mention that when you crank your amp a bit with the ES-137 you will have to watch your positioning to keep feedback under control -- not as bad as a true hollowbody, but certainly different from a true solid body. On the other hand, the rush of air coming out of the top F-hole when you crank it up has to be one of the coolest sensations you'll ever feel from a guitar -- it seems like it's actually breathing!
