Sorry man, your 3-way is a les paul type toggle like what mero said. There's NO 5-way switch in that style.
But what you CAN do is do what I did.
Replace a pot with a pushpull pot for coil splitting.
That would give you a good range of tones to play with.
However, the thing is, your switching is using an Ibanez frequented switching... its
1) Neck
2) Neck + Bridge coil split, inner coils, in parallel
3) Bridge
Thing is, I'm not clear how putting in the pushpull pot for coil spilt will function then, since there is already a wiring for coil split in the stock wiring. What I would assume is that you will have to lose the stock position 2 wiring so you'll end up with:
1) Neck (Split inner coil with PushPull)
2) Neck + Bridge(Neck + Bridge coil split, inner coils, with PushPull)
3) Bridge (Split inner coil with PushPull)
Not too big a lose, in my case, since I'm using that wiring.
Note you have 3 pots right? 2 vol. and 1 tone
So lets add in another push pull for out of phase.
Add it to the bridge hum (or neck).
Note that the out of phase switch acts as a
coil selector when the bridge pup is selected alone (position 3)
and split. So you can choose btw the inner coil or outer coil. Extremely useful when you got a pup with 2 coils with different eq/character, ala a Tonezone/PAF Pro.
And if you wanna go overkill... you can prob throw out a vol pot and put in 1 more push pull for the EMG-EXG active control... the is bascially a control that scoops your mids for some nice rhythm (or split coil stratty tones) and you can up the mids for some thick lead work. The SZ is already a mid heavy axe.
So if you do all 3, you'll get this.
1 vol pot with push pull for coil split
1 tone pot with push pull for phase
1 EMG-EXG
And your guitar will be very versatile. I think you'll spend like what, $100 for the stuff, all at once at Davis.
Btw, thor, the SZ isn't like the S series... different switch and body thickness ...
