I've got one in a reissue Les Paul Junior, single bridge pickup, all mahogany with the late 50s neck. The Supermassive 90 is, well, super massive. Give it gain and the thing absolutely roars. It's rather bass-heavy and thick, but even with the tone rolled completely off the notes are clear and defined, not muddy in the slightest. Of course, a neck pickup would probably lose some definition if you did the same thing, but I don't necessarily thing that's a bad thing.
