Yeah, that's one of the cool things about those StratCats: Fairly easy modding the controls.
Mine off factory has one tone control for the neck pup,; the other hooked to the bridge pup.
As such, I can have separate tone from either end-point, i.e.e neck or bridge, and, when using neck+mid or bridge+mid, can have yet different sounds.
If I dime down a tone control too much, both the pup it directly controls, and the parallel connection with the mid pup, will be subjected to almost the same soundscape; however, if I díme it down just right, that pup standalone will have it's tone, and the parallel connection will end up different.
As such, I can have the five pup switch positions going from, say, a slightly softened neck, a fairly crisp/open neck+mid, a fully natural sounding mid pup, a slightly subdued and yet open but also slightly more hard sounding mid+bridge tone, ending at a bridge rolled off just enough to not be too aggressive and still cutting enough for solo works.
I know others hook one tone pot to the mid pup to be used simply as a separate volume, so that they can sortof define the balance between bridge+mid or neck+mid.
I need to work out how to obtain the classic 'milky white' sound, like I remember it from old Pink Floyd songs.
If I do get it, I'll want to hook this tpone control to neck and bridge, so I can flip the switch fast to have sortof the same color, just with different hues, like bridgy milk or neckish milk expressions, or the more classic open treble-peaking tone.
And then hook a Bill Lawrence Q-filter style tone control to the mid pup for a whole slew of more rock-like options.
