Such a sweet bass, which made me want to get a bass with a maple board. Let me know how you like the reverse P on the gig. Mine's standard P inside, but they're reversible (benefit of the big shells), so I might give reverse a whirl sometime just for fun.
I really love this design...it's just an ultimate rock bass for me. Hearing the two basses at Martin's workspace, I thought our two basses had pretty different "personalities" sonically, but both were stellar.
I've been a P-bass/Stingray guy for decades, and my other 6 basses reflect that:
Obviously, with the Keith purchase I was looking to add something a little different for my collection, so I went with reverse P because I already have 3 non-reverse split-P basses. I spent half of tonight's gig on the reverse P, half on the MM pickup. In short, I agree there's a huge difference between reverse and non-reverse, but even though reverse is more modern to my ears, it still sounded great for Motown/classic rock (and so did the MM pickup).
I'll give a full gig report later, but the bottom line is that I am thrilled with the bass. As different as the Keith is from my others, its Fender-style ergonomics made it familiar enough and comfortable. Slapping a 24-fretter is a bit of a challenge, but I only slap on a few songs and it wasn't a big deal to adjust, I'm sure I'll soon get to the point where I don't have to think about it. Likewise, the extended fretboard threw my frame of reference off a couple of times when I made jumps to the high register, but again, just gotta practice with "Pearl" a little more. Again, I'm thrilled. I got the action set where I wanted, I love the neck profile, the tones were killer! And yes, it's a sexy instrument too.

I tuned it down a half step for use with my hard rock band. The purpose (as noted just above) was to gig it with my rack rig rather than my mini-rig. The mini-rig sounds nice, but my big rigs sound glorious! Isn't just a volume thing, either.
