    "best_for": "Rock and metal players who want a high-output passive bridge humbucker with tight low end and cutting highs for aggressive rhythm and lead work.",
    "who_should_skip": "Players seeking vintage output, low-wind PAF-style tone, or active pickup characteristics; the SH-6b is voiced for modern high-gain styles.",
    "fit_notes": "Standard humbucker routing required. A matching Distortion neck model is available, and the 4-conductor cable enables coil-split and parallel wiring. Choose the Trembucker variant for Floyd Rose or wider vintage vibrato string spacing.",
    "watchouts": "High DC resistance (16.6k) yields a hot signal; pair with a suitable neck pickup (Distortion neck, '59, or Jazz) to avoid output imbalance and phase\/polarity issues. Verify coil polarity when mixing with other brands.",
    "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?"]
