Re: Duncan special models for other companies? Hamer, Benedetto, any others? do u lik
Close, but not quite! The pickups in the Ibanez SZ2020 are custom versions of the TB-6b (Distortion) and SH-1n ('59) models. They were specially configured for Ibanez and only available in the SZ2020 and SZ4020 Prestige series guitars.
It gets confusing because some mid-level Ibanez "SZ" models came equipped with Duncan Designed pickups with a very simiilar appearance and even similar specs. Look closely, however, and you can see the most obvious difference...the ones on the SZ2020 say "Seymour Duncan", while the cheaper pickups only say "Duncan".
The SZ2020 pickups are also labeled "TB-6b IBZ" and "SH-1n IBZ" on the bottom in the traditional Duncan USA manner, whereas the import versions usually have a larger sticker with the "HB103B" and "HB101N" designation.
The imported "Duncan/Ibanez" bridge is a regular HB-103 wind fitted with Demon-style hex pole pieces. This model later emerged as the "HB-112" on Duncan's website and was found stock on the Fender Squier Vintage Modified HSS Strat bearing the typical "Duncan Designed" logo.
The HB-112 and the TB-6b IBZ are similar in that they both use a standard Ceramic magnet, not the double-thick type, but the winds
are slightly different and the quality is generally quite a bit better on the USA versions (though I don't have any major complaints about the Duncan Designed variants of the past few years).
The "Duncan/Ibanez" neck was just a plain 'ol HB-101n with standard slugs and fillister screws, while the SZ2020's version was the real-deal '59 model with the addition of black coated slugs to match the looks of the bridge.
Glad you're liking the HB-112, though! I own all of the pickups mentioned above and the HB-112 still holds its own!
