Pickup Character
A remarkably articulate vintage-output humbucker delivering open dynamics, fast transient response and exceptional note separation. Balanced coils create a smooth, musical voice with focused lows, expressive mids and sweet, extended highs, making it equally inspiring for pristine cleans and expressive overdriven tones.

Strong Character
Magnet density (mT) describes the magnetic field strength at each pole and how the pickup interacts with the strings.
Different magnet types have different ranges (e.g. Alnico ~30–65 mT, Ceramic ~60–90+ mT), and some variation is normal — even within the same pickup.
Typical pole-to-pole variation is ~5–15 mT.
Spread describes this:
Lower spread → more even response
Higher spread → more character and dynamics
Slugs → smoother field
Screws → more focused response

This humbucker demonstrates an exceptionally well-balanced electrical and magnetic design, producing a highly musical vintage voice with impressive articulation and dynamic responsiveness. Both coils are closely matched in DC resistance (5.6 kΩ / 5.5 kΩ) and inductance (2.12 H / 2.09 H), resulting in outstanding phase consistency and efficient series operation.
Individually, each coil exhibits a high resonant frequency around 4.7–5.0 kHz with strong Q factors, delivering crisp attack, excellent note separation and abundant upper harmonic detail. When connected in series, the pickup settles at approximately 3.5 kHz resonance with 3.52 H inductance, creating a fuller midrange while preserving remarkable clarity and openness. The measured internal capacitance and resonance behavior indicate a healthy, well-functioning winding with excellent bandwidth and controlled damping.
The magnetic system contributes to the pickup's expressive character. The screw coil provides a focused and articulate response, while the slug coil offers slightly stronger magnetic coupling that enhances sustain and harmonic richness. Together they produce a balanced magnetic field with excellent string-to-string definition and consistent output.
Overall, this is a highly expressive vintage-style humbucker that delivers articulate cleans, rich harmonic complexity and outstanding dynamic response, making it an excellent choice for players seeking clarity, versatility and musical touch sensitivity.
