Pacificas with plywood bodies have never existed, and this includes the bottom-end model, the PAC-012.
PAC-012: multi-piece agathis body (usually a 5-piece body)
PAC-112, PAC-112M, PAC-112J: 3-piece agathis body
PAC-112V series: 3-piece alder body
PAC-212B series: 3-piece alder body
PAC-311H: 3-piece alder body
PAC-510V: 3-piece alder body
PAC-611 series: 3-piece alder body
The various Pacifica USA models: 3-piece alder body
The Pacifica was designed about 25 years ago by Yamaha in the USA, in Hollywood to be exact. The goal of the design was to create the most ergonomic and user friendly double cutaway body outline (i.e. -- "Strat") with bevels in just the right places (i.e. -- belly and forearm cuts).
The same thing was done for a Tele-like single cutaway body. Unfortunately, the PAC-102 and similar Tele-like series Pacificas are no longer made -- with the exception of the Mike Stern signature model.
You're actually describing coil splitting, which is a lot more common and generally more useful than coil tapping.
