    The RGA42FM trades the RG's tremolo for a fixed bridge, giving a more direct, resonant feel favoured by heavier styles. Ibanez's fixed bridges on the RGA line are typically their own Gibraltar-family design rather than a Strat or Tele-style bridge, but the exact model and string spacing on this guitar haven't been confirmed, so check before assuming a generic fixed-bridge replacement will fit.

    Quick facts

    Tailpiece

    None (bridge-integrated)

    Neck mounting

    Bolt-on

    String spacing

    54mm (2-1/8")

    Scale length

    25.5" (648mm)

    Tuner hole size

    10mm (25/64")

    Nut width

    43mm (1.693")

    Not published by Ibanez: bridge mounting spacing. Measure this before buying a bridge.

    Watch out

    One source cites a 62mm bridge string spacing figure for this model, which is unusually wide compared to typical Ibanez fixed-bridge spacing and was not independently corroborated, so it has been left out of the clean spec field rather than treated as confirmed.

    Hipshot Ibby FP 6-String Guitar Bridge

    Likely drop-in

    This is Hipshot's dedicated retrofit for your exact stock bridge style, not their generic fixed bridge. Reuses your existing mounting and string-through holes.

    Why we say this

    Stock bridge confirmed as the Ibanez F106 fixed bridge. A generic Hipshot fixed bridge does not share the F106's mounting or string-through hole pattern, per multiple independent owner reports (SevenString.org, JEM forum). Hipshot sell a dedicated F106 retrofit, the Ibby FP, with its own published spec sheet confirming the hole match, referenced directly by owners on the Ibanez JEM forum as the correct part for this bridge style.

    DiMarzio PAF 36th Anniversary Humbucker Set

    Likely drop-in
    Soldering

    Standard humbucker footprint, direct fit for the stock HH route.

    Seymour Duncan Saturday Night Special Humbucker Set

    Likely drop-in
    Soldering

    Fits the standard humbucker route. A popular pick for this style of guitar, needs soldering.

    Why we say this

    Guitar confirmed as HH, standard humbucker route and mounting. Same reasoning already applied to this pickup set on other standard-humbucker-route guitars.

    Gotoh SG381 Tuners (Standard, Non-Locking), 6-in-line

    Likely drop-in

    Schaller M6 Locking Tuners, 6-in-line

    Likely drop-in

    Fits the existing 10mm tuner holes without any drilling.

    Why we say this

    Guitar's stock die-cast tuners confirmed at 10mm bore, consistent with the well corroborated MIJ Gotoh-made standard across the Ibanez RG/RGA family (multiple independent forum reports). Schaller M6 requires 10mm pegholes per Schaller and StewMac spec sheets.

    Hipshot Grip-Lock Enclosed Locking Tuners, 10mm post (6-in-line, Staggered)

    Needs verification

    Hole size should match, but this guitar has a pointed reverse headstock where aftermarket tuner screw holes sometimes do not line up with the factory ones. Worth checking before ordering.

    Why we say this

    Ibanez pointed reverse headstock. Owner reports on this headstock style describe aftermarket tuner screw holes not lining up with factory pilot holes even when post diameter matches.

    Gotoh SD91-05M Magnum Lock

    Gotoh SD91-05M Magnum Lock

    Requires modification

    This tuner is sized for vintage tuner holes, not the modern holes on this guitar. You'll need Gotoh's conversion bushings, sold separately, to fit it.

    Why we say this

    This tuner is vintage-hole spec (8.73 to 8.8mm), not the modern 10mm hole this guitar actually has. Gotoh sells conversion bushings separately for exactly this situation. Not a direct swap, but not a drilling job either, it is a bushing change.
