Yes but if I want good quack then if I lower the middle pickup its gonna sound too thin. Trust me, I have tried this before and that is why adding a second volume control is in my radar. If I want good quack want to crank the volume for the middle pickup, if I want less gain I will back the volume of the middle pickup. For most humbucker when you split it it is already thin sounding so if you lower the middle pickup the quack is too thin, or at least that has been my personal experience so far, maybe I need to try higher output humbuckers for which split seems to be better.
Another thing you might be able to do, that probably easier to manage, is just add a resistor to the middle position of the switch, so that the volume is lower when in the middle, that way you would still get full volume quack in 2 and 4.
You would only have to switch to the middle, not turn a knob and switch every time you want clean.
This might take a superswitch, but I bet if you ask some people around here could advise.
You could get a few 50K Ohm resistors and wire them in series until you get the sound you want.
