I know, Epi doesn't know how to make basses either, they just sell a few. If you listen to the bass run at the end of the Sam Ash vid then that is not bright, bony and thin to me, but a full sound with perhaps more presence than you would expect on a TBird. Maybe that is what they wanted, both pups seem to be eq'ed full throttle. The TB Plus on this Epi is not closer to the bridge than on a Gibson IV or V where it did fine service. TB Plus pups are full sounding pups, in comparison to other pups perhaps even a little too phat for current tastes. A lot of people - Nikki Sixx! - tend to use both pups full on, so combining a very bright position with a bassier one it not per se madness. Besides, I like the picking room that has been created between the two pups by pushing that rear pup to the bridge. Who knows, it might be the sweet spot to hit the string, right there where a Ric player would like to but regularly can't without removing the cover.
I'm Epi's defense attorney here.
