Yes made a yuge difference. I know much great music has been made on "stamped saddles" but i can't stand them.
Brass sustain is way better,thats why Yngwie & Sykes prefered brass nutts.
You can get brass saddles roller or non roller shipped from Amazon for around $30 bucks for any guitar including PRS.
Amazon has shitloads of guitar parts AND guitars including Lynch ESP Desert Eagles which tripped me out.
Be sure to measure width for correct fit. Blueberry burst is okay but wish i had the purple.
