I was taking a look at the JA 15 on the PRS website. The overview says it comes with 53 10's, but the spec page says 57 08s. I have three quick questions? Which one is it? Why not the the archtop treb and bass pups? One last question. I asked before, but got no response. What is the output of the archtop pickups? When I read archtop, I think jazzy sounds. Which is great! I am leaning towards ordering a private stock 12 string or JA 15 at years end if everything goes right and I need some background on these pups. Thank you.
