Tone Newbie: Steve Harris P bass question
I have been playing bass for about 5 years but it has mostly been a gradual learning process outside of proper playing technique (I mainly play guitar). I am learning more about tone now and I am enjoying all the eureka moments of "ohhhh thats why that sounds so different even though its the same gear" kinda EQ moments etc.
I have a Sterling Stingray and I love it. Up until now I have honestly not seen any reason to explore other basses. As I've been digging into tone, though, I'vs noticed a couple things I don't understand.
One is that Steve Harris from Iron Maiden uses a P Bass, and that he uses Flat Wound strings. I haven't used either of those pieces of gear, but I was under the impression flat wounds were more associated with jazz tones, and the P Bass was also not something I figured he'd use. Is there a logic to his choosing these for his tone?
If these are naive questions please excuse the newbishness :) there are only so many hours in the day so I learn what I can when I can! Thank you!
FOLLOW UP QUESTION:
I'm a massive Black Sabbath fan. I feel like Geezer's tone is much different than other hard rock and metal players, EG on Master of Reality. He has a much smoother tone that doesn't have the high end clack that Harris has. What is the logic behind this, EG why would he choose to do this and how does it successfully cut through the mix without turning it into mud (actually its Sabbath, so I should say sludge).
