I had a strat with Duncan JB for a long time and I never liked the quacky nasal quality it had, though the harmonics are great. Got a new Mexi strat and I put a Duncan Custom Custom (yes, 2 "Custom"s). Their description calls it good for thickening up a thin guitar and, though my strat was not particulary thin, it now has more beef. Fat, hot, great overtones and harmonics, and no nasal quack. Paired with a JB Jr. in the neck, that strat rocks my socks.
Do good and fear naught.
If I disagree with you, it is because you are wrong.
