I have a Fender MIM P with Duncan Quarter Pounders. My band tunes down 1/2 step to accommodate the singer. I play DR Black Widows. My tone has been really muddy. Here's my question: Can it be the tune down causing the issue? I know Ps are not at sharp and growly as a Jazz, but I would think I could still get a bright tone even tuned down a half step. Should I change strings? Should I change gauges? Should I just sell it and get a Jazz? Opinions please.
