I opened up a strat with 2011 Custom Shop AY pickups. They meter at 5.2 each. Found a 500k tone pot (literally meters 504k) and a treble bleed. The guitar sounds more Stratty than any I've played. Real stringy and acoustic, super-quack, all that. But it IS trebly (maybe that explains the magic?) and powerful, and my question is, is 500k plus treble bleed a common approach? Or did this luthier really experiment until he got just what he wanted?
