Re: PRS McCarty soapbars
My advice would be to measure the resistance of the SD that is in the neck right now and get something that is wound a fair bit less hot, and preferably something with an A5 mag. A2 magnets are usually a bit fuzzier and warmer with A5 being more on the clear side, and P-90s tend to get looser and less focussed with more windings on the coil. Depending on how hot your current pickup is, I recommend the SD Vintage Soapbar Neck Model.
