First off let me say I'm a huge BKP fan and now have them in all my guitars. I'm waiting for my Irish Tours to make it a complete set. I go on a Les Paul board and all these guys are buying these $100.00 to $125.00 wiring kits. 4 pots and the caps to go with the set. They say "this is the best upgrade I've ever done" is this the Emperor's newest clothes, or does changing pots and caps really make a big difference over stock Gibson parts?
