Just put some in an Epi LP for a customer.
They are indeed better than I than my previous experience indicated.
Acoustically the guitars a lot middier and quite a bit bassier than the previous one I tried them in, and they have a thick punchy low mid that didnt come out last time I tried them (presumably because the guitar didnt have it - cant pickup whats not there), they have a strong attack, quite even sounding in this guitar, and are tighter too.
I like.
Not enough to replace any of my other high output BKs with, but I like.
Lesson learned (well, revised - BKs sound very different in different guitars).
That will be all.
