    This won't fix the well-known radius mismatch on this guitar's stock bridge, but it upgrades the rolling saddle mechanism, which reduces string binding and tuning slip. A tech filing the stock saddles to match your fretboard curve is the more common fix for the radius issue itself.

    Why we say this

    This guitar's known factory issue is its Tune-O-Matic-style bridge sitting at a 12 inch radius against a 9.5 inch fretboard, and owner communities specifically discuss this roller bridge as one of the few still-available options for the same general bridge family. It does not fix the radius mismatch itself, and exact post spacing has not been independently confirmed against this specific guitar. Other commonly cited fixes (Wilkinson rollers, which only come in 14 inch radius, and a StayTrem replacement that multiple recent owner threads report as discontinued for this guitar) are not real current options and are deliberately not listed here.
