Vintage Original 1991 Seymour Duncan Alnico II Pro Staggered

Up for sale is a genuine early-90s Seymour Duncan Alnico II Pro (APS-1). This vintage-correct unit features the classic staggered pole-piece pattern, designed to balance output on traditional radius fretboards. If you’re looking to tame a "brittle" Strat without losing the chime, this is the one. The Alnico II magnets provide a sweeter, more musical treble attack and a "spongy" bass response that feels great under the fingers.

Provenance & Specifications:

• Factory Stamp: The bottom flatwork is stamped "SD 91 2", identifying this as a 1991 Alnico 2 unit—guaranteeing this is a genuine 30+ year old vintage wind.
• Model: APS-1 (Alnico II Pro Staggered)
• DCR: Measures a healthy 5.99k Ohms
• Leads: Approximately 9 inches of original cloth-pushback wire—plenty of length for Neck, Middle, or Bridge positions.
• Condition: Authentic aging on the cover and pole pieces; fully tested and ready to install.

Modern pickups are often wound on high-speed CNC machines to exact, sterile tolerances. This 1991 Seymour Duncan was built during the "Golden Era" of the company—when they were still using the legendary Leesona winding machines (the same gear used for 1950s PAFs and original Fender coils).

Why vintage is more desirable:

1. The "Sweet Spot" Output: Measuring at 5.99k, this pickup sits in the perfect vintage window. It’s not overly hot, allowing your amp to breathe and your guitar’s natural woodiness to shine through.
2. Aged Alnico 2: Magnets naturally lose a tiny fraction of their pull over the decades. This subtle "de-gaussing" softens the high-end attack even further, resulting in a creamy, "played-in" tone that a brand-new Alnico 2 pickup simply can't replicate out of the box.
3. Ironclad Authenticity: Unlike later models with generic stickers, the "SD 91 2" bobbin stamp is a permanent mark of quality from a time when Duncan’s production was smaller, more hands-on, and focused on replicating the pre-CBS magic.

This isn't just a replacement part; it’s a 30-year-old piece of tone history that’s already "broken in" and ready to give your Strat that elusive vintage mojo.

About me: I have been a guitar technician for over 3 years now, and during that time, I have acquired many cool and rare parts over the years, and have decided to begin selling them to fund other guitar projects. Let's Get Guitarded (also on Ebay, Craigslist, and FB MP) is my store where I do that, and I'm always happy to help other guitarists get to where there want to be. I eat, sleep, sweat, and bleed electric guitar. This is my passion. Thanks for checking out my listing, and please check out the rest of my store, I have a lot of cool stuff!
