Alnico II magnet
A softer magnet than Alnico V. Less string pull and a rounder attack rather than a sharp, aggressive edge.

Independent shopping perspective

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
A softer magnet than Alnico V. Less string pull and a rounder attack rather than a sharp, aggressive edge.
Detail 02
Wound hotter than the matching neck model to balance the thinner string swing near the bridge.
Detail 03
Metal cover shields the coils and matches nickel hardware. Covers slightly tame the very top end.
Detail 04
Single full-size humbucker. Drops into a standard humbucker route; no pickguard or body work needed.
Detail 05
The resonant peak sits high, so treble detail survives despite the cover and the moderate output.
Detail 06
Mid-tier for a covered humbucker. A matched neck pickup is a second purchase at similar cost.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is the APH-1b Alnico II Pro, a separate model using an Alnico II magnet. The two are voiced differently despite both being vintage-output.
Yes, if the route is a full-size humbucker cavity and the pickguard opening matches. Check whether your pickguard mounts the pickup or the body does.
Covers can be desoldered and removed, but that is tech work and risks damaging the coils. Buy uncovered if you want that look.
Not required, but mixing it with a much hotter neck pickup will leave the two positions unbalanced in volume.
