well I`m no pro, not even close but I own and love my USA II and Pacifica 10th anniversary...similar to the USA II but with Duncan single coils instead of the Vintage Rails. Warmoth necks and bodies, Duncan p`ups, Schaller locking tuners, Wilkinson bridges...come to think of it, `bout the only thing Yamaha about em is the MOP inlayed logo on the headstock. Also have the MS 1511 Mike Stern and an SA2200 plus an SAS 1500 as well as several acoustics...love them Dynamics... and a couple of older SG types. BIG fan of the Yamahas...for these amateur hands and ears they sure are great guitars.
