Please Help.
What does Vintage Stagger mean? Flat profile?
Flat profile means that all of the poles on the pickup are the same height. Staggered means that they are different heights. I would go with flat for that setup.
Stock polarity? RW/RP polarity?
RW/RP = Reverse Wound/Reverse Polarity.
When you use a reverse wound coil with another single coil, it acts like a giant humbucker, cutting down on the noise on the in-between positions of the 5-way switch your Ibanez has.
When you select positions 2 or 4, you are using the inner coil of the bridge or neck pickup as well as the middle pickup simultaneously.
I don't like the sound of RW/RP, but plenty of people do.
Thank you.
You're welcome. :)
