This is a must have switch for a 3 pickup guitar.
Since I never use the middle pickup on my guitars I do the following.
In my SSS strat the middle position is neck/bridge . A far more usable tone like a Tele than the middle pickup alone.
On my Nashville tele you get the standard tele sound in the middle position !
The best one !
On my 2nd Nashville Tele HSS you get 2nd position bridge/middle with split coil and in middle position you get neck/bridge split coil.
I use to have push,,,pull,push,push,toggle switches before but this thing is a godsend,clean and easy to install.
A must have for your guitar !
