Phil Jones, the original LP designer, thought the Bart TCT harness was - back then - God's gift to bass electronics, he put it pretty much in any (even slightly) upscale model (later LP Specials, all LP Deluxes, early pre-toggle-switch LP Standards, EB-750, LP Doublecut Prototype, Primavera Prototype, Smartwood LP). Hardly any bass escaped!!! He once wrote to me "that it was a good harness at its time, when such things weren't so widely available", so I detected some remorse in that!
I guess his quest was to make a true Gibson bass, set neck, maho and classic shape and all, yet one that would sound "modern" in the early nineties to appeal to perceived tastes. Let's forgive him, we all err once in a while, he's a nice man and has always been helpful to me. Nobody else
on earth owns a korina TBird, so there!
But look at all the good things I did too!
