GroovyThere should be a silver sky specific volume pot available on the PRS spares website. The 500k would normally be for the humbucker guitars. I was looking through the UK PRS site a couple of months ago and sure I saw one for the silver sky. However, I bought the 500k one for my Strat (that has all single coils) and that's working for me but that does have a higher output darker bridge pickup which I wanted the 500k to add a bit of presence on the top end
Thank you for the input, good sir!
