The Seymour Duncan TB-4 JB is identical to the SH-4 JB bridge pickup, but with Trembucker spacing for guitars with greater than 2.00" string spacing (E to E) at the bridge. The Seymour Duncan TB-4 JB Trembucker has been the archetype hot-rodded humbucker for over 30 years. Great for everything from heavy blues to heavy metal. The TB-4 JB is the world's most popular humbucker. Provides slammin' output while retaining singing highs, aggressive harmonics, and just the right blend of sustain and distortion. Goes from sweet warm tones to raw rock 'n' roll. Compared to the SH-14 Custom 5, the JB has a stronger treble detail. Some players use it with 250K pots to smooth out the highs. Comes with four-conductor hookup cable. Available only for the bridge position. Often a JB is paired with a neck pickup like the SH-2n Jazz (Seymour's favorite) for versatility or a SH-1 '59 for P.A.F. tones. Suitable for balanced and warm instruments. Works especially well with rosewood fingerboards. Players include Paul Stanley / KISS, Gary Rossington / Lynyrd Skynyrd, Ty Tabor / King's X, Steve Marker / Garbage, Nick Hexum & Tim Mahoney / 311, John Connolly / Sevendust, Dave Mustaine / Megadeth.
