Ok, so I like the extra low notes of D standard and find it easier to sing in that register as well. I also actually like a bit of slack in the strings when using a standard 45-100 set of boomers on my P Bass. Here is the question... Assuming I stick with the P bass, what can I do to get more clarity and snap when using this tuning? I find that when I lay on the fuzz and even clean my faster runs get muddy when tuned to D. Is it as simple as a heavier set of strings or should I be experimenting with different brands or maybe stainless steel? Different pickups maybe or would that not help get a bit more clarity and snap? We play groovy sludgy rock/metal but as a three piece I want to play a bit more "lead bass" and need some clarity and snap like a guitar would have.
