    "best_for": "Players chasing Eddie Van Halen's original Frankenstein tone at the source: this is wound to the exact specs of the pickup in his original Frankenstein guitar. Its 14.4 kOhm \/ 9.4 H high-output coil paired with a softer Alnico 2 magnet suits hot-rodded bridge-position rock and hard-rock playing, and the standard humbucker size makes it a drop-in swap in any standard humbucker rout on a 6-string.",
    "who_should_skip": "Skip it if you want coil-splitting, phase switching, or auto-split wiring schemes — the vintage-style single-conductor braided-shield lead supports none of those (series humbucker only). Also skip if you need an active pickup, a covered\/capped look, a low-output vintage-PAF-level pickup, or a pickup for a 7- or 8-string instrument — this is passive, uncovered, high output, and 6-string only.",
    "fit_notes": "Direct replacement for standard-size humbucking pickups, so no routing changes needed in a standard humbucker cavity. Installation is soldered (no solderless connector), and mounting hardware is included in the box. Thomann specifies it as a bridge pickup; Sweetwater and FU-Tone list it as bridge\/neck compatible, so bridge is the primary intended position.",
    "watchouts": "Retailer listings disagree on the lead wiring: Sweetwater and Thomann describe a single conductor with braided shield (2-core), while FU-Tone says 4-conductor — if splitting or advanced switching matters to you, plan around the single-conductor spec we list. Soldering is required for installation. Position listings also vary slightly between retailers (bridge vs. bridge\/neck).",
    "verification_questions": ["What exact dimensions, mounting pattern, and model compatibility does this part support?","Is all required mounting hardware included?","Does installation require routing, drilling, soldering, or other irreversible work?","Is the item still in stock at the displayed price, and what is the complete delivered cost to the intended destination?"]
