Totally agree 100%. You do not realize how truly bad this design is until you spend some times playing on a Petrucci Majesty guitar, it doesn't look as good as a PRS but is probably the most effortless guitar I have to play. I own many PRS and have owned many over the years. Also, Les Paul, Charvel, Ibanez. In terms of access to the the controls fast effortlessly and on demand PRS is probably the worst. Fender Strat would be the worst but because of the pick guard you can modify it.
Don't get me wrong I do love my PRS guitars but I never play them live ever because if this. When your playing live there is way too much going on to have to add in trying to find your switches or controls in the dark or fast on demand or trying to look down when you miss a control and figuring out what you did. If your playing fast and need to switch fast. The position of the 5 blade is an issue. The 3 way is ok, you just got to remember to go up and then reach for it if your sustaining something or you will hit the trem bar. However, it you also have the little metal switches, those hurt hurt like heck. Never understood those. It is like Thumb bleeders on vintage les pauls. Lets put metal sharp corners where you hands are moving really fast and your not looking. Even push pull because if the recessed knobs can throw you. A push push would be much better and faster here.
I would love to see a total redesign of a lot of the controls.
