Anyone ever have GHS pressurewounds on their bass for a long time? Like 6 months plus. After a while, do they have all the punch and definition (or lack of) like flatwounds? or do they retain at least some zing. I like the idea of keeping strings on my main bass pretty much forever. I don't slap and don't need a lot of brightness and zing, but I'm wondering if they'll completely lose all their punch.
