I played my SKB 3005 at practice last night (Country) and it delivered a very strong P tone (nickle rounds). This bass has Noordies and an OP-3.
I don't know if Centuries have a different vibe, having owned 3 SKBs, 2 LGs (all but 1 SKB Bart equipped), but aren't Roscoes reputed to be Ptoned in general?
As for the P thing, I had a Fender P5, and a Squier VMP5, and kept the VMP5. There's a Fender loaded one in the classifieds for $375, just saying, a cheap way to scratch that itch...
Also want to add, I have a CS '59 NOS P, and a JPJ 4, a Modern Telecaster 4, and owned a Fender Roadworn P, Fender Antigua P, and a '76 P, and don't touch any 4s, including my '66J. So I don't get the gotta have a 4 crowd. My point being, I know what a P should sound like, and my VMP5 delivers (in fact I have Fender guts for it, they're still sitting unused).
