A technical hub for Asyllum pickup measurements, test protocols and controlled comparisons, separating measurable data from marketing shorthand.

Same AWG, different insulation: how Heavy Formvar and Plain Enamel affect coil geometry and electrical parameters.

From string movement to the signal sent to the amp: induction, magnets, coils, inductance, resonance and potentiometers explained clearly.

Wax potting, microphonics and dynamics: what potting is for and why some vintage-style pickups remain unpotted.

8 kΩ, 10 kΩ or 14 kΩ: why DC resistance alone cannot compare the output, tone or quality of two guitar pickups.

Reverse Wound Reverse Polarity explained: how an RWRP pickup reduces hum in combined positions and what it actually changes.

A practical guide to vintage Strat pickup families: magnets, wire, winding, RWRP, output level and pickup-height adjustment.

Alnico II, III, IV or V: what magnet grade really changes, and why the grade alone cannot predict a pickup’s tone.

Winding, bobbins, magnets and production variation: why late-1950s PAF pickups cannot be reduced to one fixed specification.

Why a Mini Humbucker sounds neither exactly like a PAF nor a P90: coils, magnetic window, inductance and practical uses.

Coil geometry, magnets and dimensions: what separates a true P90 design from a pickup that simply fits a humbucker route.
