I recently put a set of GHS Boomers on my MIM P-Bass and after playing like 4 church services, I don't practice as much as I should on electric, they sound almost like Flatwounds. Is this usually how it goes with Boomers? I've noticed I haven't seen them on the BG board very much. I like the sound new, but they just totally died on me after not that much playing time. Which strings have a similar sound and feel but last longer?
