Yamaha Pacifica is the name of a series of electric guitars manufactured by Yamaha. The line was originally designed in Yamaha's California custom-shop by Rich Lasner, working with guitar builder Leo Knapp. Initially intended by Lasner and Knapp as a test project, Yamaha Japan chose to produce the instruments.
Pacificas all have one of two basic body shapes: a Stratocaster inspired double cutaway shape, or a Telecaster-like single cutaway. Apart from these similarities, the models vary in materials, hardware, and electronics. As of December 2009, there were currently 5 models in production.
The best-selling and most recognisable models are the entry-level PAC012 and PAC112. The 112 has a solid Alder body and has always been available with a clear varnish finish, showing the grain of the wood. At the time of the original launch this was intended to contrast with some of Fender's budget models, which then used cheap plywood for the body. The entry level PAC012 has one Yamaha humbucker and two single coil pickups, an agathis body and a Strat-style vibrato bridge.
The early PAC1412 and PAC1421 models had set necks and carved tops with Floyd Rose locking vibrato bridges. These guitars were ultimately too costly to produce and hence too expensive for Yamaha's market. Other variations include the twelve-string PAC303 12, and the reversed headstock PAC721R.
The high-end PAC1511MS has a solid swamp ash body, with a Seymour Duncan humbucker neck pickup, and a Seymour Duncan "hot-rails" humbucker pickup in the bridge position, and a non-vibrato bridge with strings passing through the body. The entry level version of this Mike Stern signature model Pacifica is the PAC311MS. Both are Telecaster-style guitars similar in shape, but in the case of the PAC311MS controls are slanted rather than on a chrome plate parallel to the strings and the M stands for Maple (neck) and the S for Singlecut as there also was a PAC311S with a rosewood neck. While the production of the 311MS and 311S lasted only a couple of years at the beginning of the nineties, the 1511MS has remained in production. This illustrates how some Pacificas were lower or higher priced versions of conceptually similar guitars.
The 904 model featured a Warmoth produced neck with a compound radius, locking sperzel machineheads, and a push push tone control (like the 604W and 604V) that split the front dual single coil pickup into a single one. The Body was an ash slab top on an alder back and featured a highly engineered neck joint.
At the 2011 Frankfurt Musikmesse Yamaha announced the 611HFM, 510V and 311H models and the reintroduction of the 120H. The 120H is similar to the 112V, but features a hardtail, instead of a tremolo bridge, and a pair of humbucker pickups.
