I had a custom shop strat that was shrill as hell. Fralin Hot Blues were not an improvement.The tone controls did very little. Then I played (and bought) a John Mayer strat. The tone controls let me get a nice tone in any pickup combination. I can roll off just the right amount of highs, even the bridge pick up solo. I believe it's due the 0.22 uF cap + pickup interaction. Strat's always seemed finicky to me, and I prefer to own one that doesn't need "improvement". I've played many strats of all vintages and models, and for me, the guitar either "has it" or it doesn't. You can spend a lot of money and not get what you are after. And I will never forget a stock Tokai I played 25 years ago that was cheap and one of the best sounding stratsI ever played. And the hundreds of strats I played since, very few of which came close.
