Bridge Type
Approx. Length
ABR‑1 (ABR)
Shorter, narrower footprint
Vintage design; limited saddle travel; lighter.
Nashville
Longer, wider footprint
Modern design; more intonation range; larger body and saddle slots.
Farber is ABR-1 sized. You can also top wrap the stop tail for better clearance, but the disadvantages are scaring the surface and if your style has your palm scraping over the strings, not too comfortable.
Nashville bridges are physically longer because the housing is wider and the saddles have more room to move.
ABR‑1 bridges are more compact, which is why vintage Gibson spacing and post locations differ from Nashville-equipped guitars.
