What guitar types does the PA-TB1B fit?

The F-spaced Trembucker design with 2 1/16" string spacing is built for modern solidbody guitars with standard bridge cavities. It installs as a drop-in replacement with no modification needed.

How does the PA-TB1B compare to the Seymour Duncan JB?

The PA-TB1B is the bridge-position Trembucker version of the Parallel Axis design with 15.7k resistance and a tighter, more articulate midrange focused at 4.5 kHz. The JB is a full-sized humbucker with a different voice; choose the PA-TB1B if you need F-spaced Trembucker dimensions and the articulate character of the Parallel Axis line.

What kind of tone does this pickup produce?

The PA-TB1B delivers a punchy, focused midrange with articulate string clarity and warm harmonic presence. The over-wound Alnico 5 coils generate strong output and sustain while the patented dual-pole design eliminates hot spots, making it ideal for hard rock, metal, and progressive styles.

Is this pickup suitable for studio recording?

Yes. The pickup is hand-crafted with studio-grade articulation and even magnetic field distribution, making it excellent for capturing defined, clear tone in recording sessions while maintaining the presence needed for tight, dense mixes.

What comes with the PA-TB1B?

The pickup includes a four-conductor hookup cable for wiring flexibility. It is fully assembled and ready to install into a standard bridge cavity.

Seymour Duncan Trembucker PA-TB1B Original Parallel Axis Bridge Pickup

The PA-TB1B delivers articulate, defined output with excellent string-to-string clarity across the full frequency spectrum. This F-spaced Trembucker design accommodates modern bridge spacing while maintaining the balanced response that made Seymour Duncan's original Parallel Axis design a studio and stage standard. Hand-crafted in Santa Barbara, this pickup bridges the gap between vintage character and contemporary tonal demands.

Tone & Output Characteristics

An Alnico 5 bar magnet paired with over-wound coils generates a 15.7k DC resistance with a 4.5 kHz resonant peak, producing a focused, punchy midrange that cuts through live mixes without sacrificing harmonic richness. The patented dual-pole design ensures even magnetic field distribution, eliminating the hot-spot bias common in traditional humbuckers—critical for consistent tone night after night on the road.

Design & Construction

The F-spaced configuration with 2 1/16" string spacing fits modern solidbody guitars with tighter bridge pin layouts, ensuring perfect pole-piece alignment and reliable performance across varied stages and venues. A four-conductor hookup cable simplifies wiring flexibility, and at 0.70 lbs with compact dimensions (3.00" W × 1.50" H × 4.00" D), installation fits standard bridge cavities without modification—no downtime before the gig.
