I was under the impression that the PRS SE's come with the 9 set/
I know when I put 10's on mine- I had to widen the nut a bit, the strings were binding.
In the FAQ on the PRS site it says:
"We set-up the guitars at our factory with the following string gauges:
Most solidbody instruments are factory set-up with 10 - 46 gauge strings.
The DGT is factory set up with 11 - 49 gauge strings with unwound 3rd.
The non-piezo Hollowbody models are factory set-up with 10 - 46 gauge strings.
The piezo equipped Hollowbody models are factory set up with 11 - 49 gauge strings with a wound 3rd."
Yet in the accessory shop the 10-46 gauge set is mentioned as shipping on the hollow body PRS, with no mention of the SE's. A bit confusing, & also, since the SE series is an import, it quite possibly has a different string supplier as well, although you'd think they'd want to promote their own brand as much as possible. Don't know, but I really like the set that came on the SE & I want more.
