Re: free way switch vs.fender 5 way super switch
The SuperSwitch can be thought of as 4 separate 5-way switches. Each Group has a Common, which is always connected to one of the 5 tabs in that group.
You can connect tabs from any Group to any tab in any other Group, and when the tab whose Common is being fed to the guitar's Output is selected, then that other Group's tab will also be active.
Alternatively, you can wire up the switch to behave like 4 separate 5-way switches, and you use another switching system (rotary knob) to pick which Group is active.
Group 1 = Standard 5-way Fender 3-pickup switching with no splits.
Group 2 = Same but with Auto-splits
Group 3 = Splits only
Group 4 = Humbuckers always in Parallel
Or any combination you want that can be done with a regular 5-way.
However, another critical point where the SS differs from a standard Strat 5-way:
A standard Strat 5-way is a 3-way switch with automatic bridges between the 1st and 2nd, and 2nd and 3rd positions, meaning that positions 1, 3, and 5 are "whole" while 2 and 4 are "and". Position 1 is Bridge only, position 2 is Bridge AND Middle, etc.
To make a SS do this, you have to manually join those connections to make 2 and 4 behave that way. If not, then you will get sound from 3 positions and nothing from 2 of them. This is not entirely a bad thing (i.e. kill switch).
