.. Hwy 1 has a simple bent plate vintage bridge, with threaded saddles ... Highway ONE has the BAII ..
... early American Standards (95-2000) have string through body only bridges with spriral saddles, American Series after 2001 have STB as well as top load option bridges ... AmStands (2008-current) use the High Mass Vintage Bridge (HMV .. a terrrible oxymoronic name) with both STB and top load option
... the early Hwy 1's ('03-04) used conventional Fender tone circuitry, after that (05-06) used GreaseBucket ... all Hwy ONES from 2006 until discontinued in 2011 used GreaseBucket tone circuitry ...
.. Both the Hwy 1 and ONES used the same machines (tuners) that were used on the MIM STANDARDS ... the early AmStands and the AmSeries used a different open style tuner, I believe they were from Hipshot ... the 2008-current AmStands use a slightly different, smaller, lighter machine ...
... just to clarify
