So I've had my Silver Sky since March , I fell in love with this guitar because it has amazing clean tones. Actually the PRS635JMs are pretty sweet and can out Strat my Strat when it comes to getting that spanky clean tone. BUT this guitar was always lacking when it came to high gain situations. I mean I never expected this guitar to be a high gain contender but It just bothered me that I could produce these awesome cleans , but had trouble getting a nice crunch with it . Well thats all changed now . The Jb Jr is just what this thing needed . Easy Install with amazing results . Now she sings like a canary and roars like a beast!
