I'm happy with my VTVT stacked knob setup. It did take some fiddling with setup though to get it right. 1. I ditched the detente washers that engage the holes in the bottoms of the lower black tone knobs. Those things are useless and only make the tone adjustment sweeps bumpy and rough. They were replaced with the regular flat washers used with any other control pot. 2. The top chrome volume knobs can drag or snag the lower black tone knobs. It's annoying as hell. The common fault is in the depth of the shaft holes cast or machined up into the knobs. The bore of the holes goes too deep or too high up into the knobs. It's such a simple thing. I have no idea why Fender or anyone else who might make these knobs has never recognized this simple flaw and adjusted their production tooling accordingly to solve it. I solved this for myself by making two equally short nubs or filler/spacers out of a maple dowel rod of the right diameter to be tightly press fitted up into the top of the shaft holes. With this mod the knobs bottom out on the volume pot shafts so they sit up slightly higher, but not so high as to be obvious or a problem. That eliminates the problem of the tone and the volume knobs dragging on each other so that they won't turn/adjust independently. With everything dialed in setup wise with wires, pots, cap, resistors and input jack tucked in neatly where they need to be in the shielded body cavity, along with those two changes above everything works smoothly and predictably. I have no problems with unfortunate interdependent interactions between the neck and bridge tone knobs or volume knobs.
