I have a wonderful PRS studio. It’s a great guitar, the best I ever owned: the bridge humbucker is sweet, the narrowfields are some of the best pickups I heard. My studio has in my opinion only 1 little defect: the tone pot is push pull to split the humbucker, but the crystal clear knob is difficult to pull. I have solved the issue with 2€, buying a silicon ring made for vape sticks. It’s 21-25mm diameter in size and it sticks perfectly on my pots, giving them a perfect grip. Mine has a batman logo that fits nice on my blue burst PRS Studio. You can find them on ebay, this is the one i bought but you can find plenty different colors: https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.it/ulk/itm/283049882335 You can use the rubber band without any risk to damage the guitar, and I find them very confortable.
