  "advisor": {
    "best_for": "Players replacing or restoring the bridge on a Gibson built around the ABR-1 mount — it is the genuine Gibson part, matching the design Ted McCarty introduced in 1954 that has been standard on countless Gibson models for 60+ years. Also suited to setups where you want per-string intonation control and saddles you slot yourself to your exact string gauges and spacing (they ship unnotched).",
    "who_should_skip": "Skip it if your guitar's bridge posts don't match this assembly's footprint — 2-29\/32 in (73.66 mm) post spacing with 6-32 x 1-1\/16 in threaded posts that mount directly into the body — since a mismatch means drilling or hardware rework rather than a drop-in swap. Also skip if you want pre-slotted saddles: these are unnotched and need to be filed at installation.",
    "fit_notes": "Measure before ordering: post spacing should be 2-29\/32 in (73.66 mm) center-to-center and the post holes must accept 6-32 x 1-1\/16 in threaded posts, because this full assembly's posts screw directly into the guitar body (no separate bushings are listed among the included components). String spread is 2-1\/32 in (51.56 mm) and the saddle radius is 12 in (304.80 mm), so check it against your fretboard radius for even string height across the neck. Chrome finish — match it to your existing tailpiece and hardware.",
    "watchouts": "The saddles arrive unnotched: string slots must be filed at install, which sets your final string spacing permanently, so this is a setup job rather than a pure drop-in if you've never slotted saddles. Intonation is adjusted per string at the saddles and overall height via the thumbwheels; the closed-bottom construction is a design point to note if you're matching an existing bridge's underside. Sold as the bridge assembly only — no tailpiece is included.",
    "verification_questions": ["Does the destination guitar use an ABR-1 bridge with #6-32 US-thread posts and 73.75 mm post spacing?","Is chrome BR010 the required finish and part-number variant rather than BR015, BR020, Nashville, or Historic Non-Wire?","Are the required studs, thumbwheels, and any other mounting hardware included with the exact offer?","Is the exact Next Gen Musical offer still available at the displayed CAD price?"]

    "summary": "Gibson BR010 is the chrome ABR-1 Tune-o-matic replacement bridge. Reviewed retailer evidence describes separate studs and thumbwheels, #6-32 US post threads, 73.75 mm centre-to-centre post spacing, individual intonation adjustment, and bridge-height adjustment. Do not substitute it for nickel BR015, gold BR020, Nashville, or Historic Non-Wire variants. Confirm the destination guitar's bridge family, post thread, spacing, finish, and required hardware before purchase. Exact factory package contents and a current manufacturer product page remain unresolved. Envoy Music does not stock or fulfill this external reference.",
