I own 5 single coil P Basses (including the AO '54).
Sound wise, the single coil pickup has more clarity, definition, tighter lower bass and some slight 60 cycle hum when the tone control is set to high. I actually really like the pickup's sound. By rolling off the high end a little bit, it starts sounds much like a split coil P Bass.
I do not like the 2 saddle bridge! The D and A side of the saddles are upward to match the neck's 7.25" radius. Thus, the saddles are slanted downward to the E and G side. This can cause when playing, all four strings to slide downward to the low end of the saddles. This is very annoying. I've used pull ties behind the saddles to hold the strings in place. Or, one can buy a 4 saddle string through body bridge as a replacement for the 2 saddle bridge.
The SCPB's necks are thicker............love it!
I love the the SCPBs! I love the split coil P Bass too!
