Seymour Duncan JB Trembucker / Jazz — Complete Floyd Rose HH Coil Split Kit

The Seymour Duncan JB Trembucker / Jazz Complete Floyd Rose Coil Split Kit is the complete tonal solution for Ibanez, Schecter, ESP and any other HH guitar fitted with a Floyd Rose or double-locking tremolo system. It combines the TB-4 JB Trembucker — the wider-spaced Floyd Rose version of the world's most popular humbucker — with the SH-2 Jazz neck pickup, a push-pull coil split wiring harness and your choice of switching format. Everything in the signal chain is upgraded. Nothing is left to the original electronics.

Why Trembucker Spacing Matters — The Technical Explanation

All Seymour Duncan humbuckers are available in two string spacing formats. The standard series — designated SH — is built to 1.90 inch pole spacing, correct for fixed bridges, wraparound bridges and vintage-style tremolos. The Trembucker series — designated TB — is built to 2.07 inch pole spacing, correct for Floyd Rose double-locking tremolos, Ibanez Edge and Lo-Pro Edge bridges, Kahler bridges and similar wide-spacing systems.

The pole spacing of a pickup must match the string spacing of the bridge for optimal performance. When the strings pass directly over the centre of each pole piece the magnetic field captures the full vibration of the string. When the outer strings sit off-centre from the pole pieces — as they do when a standard-spaced humbucker is fitted to a Floyd Rose — the pickup captures less of their vibration. The practical result is a bridge pickup that sounds strong and balanced on the middle strings but thin and weak on the high E, with uneven dynamics across all six strings.

This is not a subtle difference. It is immediately audible. And it is entirely avoidable by using the correct Trembucker format in the bridge position.

The Pickups — JB Trembucker Bridge / Jazz Neck

TB-4 JB Trembucker — Bridge

The JB humbucker is the best-selling aftermarket pickup in the world — used across every genre from blues to metal and found in the bridge position of more guitars than any other aftermarket humbucker. Its character is immediately recognisable: aggressive, articulate and harmonically complex with a midrange peak that cuts through any mix and a top end that allows pick attack and harmonic detail to come through clearly even under heavy distortion.

For the lead player the JB's harmonic content makes pinch harmonics and natural harmonics accessible and expressive — the pickup actively encourages aggressive technique. For rhythm playing the low end is tight and defined rather than loose, making palm-muted riffing clear and punchy. The TB-4 is the JB in every sonic respect — identical wind, identical magnets, identical character — built at Floyd Rose string spacing.

• Output: Hot — suited to hard rock, metal, heavy blues and high gain playing
• Character: Aggressive, articulate, cutting midrange, harmonically complex
• Magnets: Alnico V
• DC Resistance: 16.4K
• Conductors: 4-conductor plus shield — coil split ready
• Spacing: 2.07 inch — correct for Floyd Rose and wide-spacing bridges

SH-2 Jazz — Neck

The Jazz humbucker is the most widely used neck pickup in the Seymour Duncan range and the natural complement to the JB bridge. Where the JB is hot and aggressive, the Jazz is smooth, warm and musical — a full, open neck tone with excellent note separation and a natural, singing quality that suits clean playing, melodic lead work and the warm rhythm tones that make a neck pickup worth using in the first place.

The Jazz is standard spacing at the neck position — the string spacing at the neck of virtually all guitars is narrow enough that standard spacing is correct regardless of the bridge format. The SH-2 Jazz is 4-conductor, enabling full coil-split functionality through the push-pull volume control.

• Output: Medium — balanced, smooth, musical
• Character: Warm, full, excellent note separation, singing lead tone
• Magnets: Alnico V
• DC Resistance: 7.7K
• Conductors: 4-conductor plus shield — coil split ready
• Spacing: Standard 1.90 inch — correct for neck position on all guitars

Coil Split Wiring — One Push-Pull, Full Tonal Range

Both the TB-4 and SH-2 Jazz use 4-conductor lead wire — which means both pickups can be coil split. This kit wires the coil split to the push-pull volume pot. Pull the volume knob up and both pickups split simultaneously to single-coil mode. Push down and both return to full humbucker operation. The 3-way toggle switch handles all pickup selection — bridge, both, neck — independently of the coil split function.

This gives the guitar four distinct tonal configurations:

Choose Your Switch Format — Same Kit, Same Price

Different HH guitars use different switching formats. This kit is available with either switching option at the same price — specify your preference when ordering.
