Description
If your low B feels thin or your P-Bass tone runs out of steam under a heavy right hand, the Quarter Pound is the fix. It’s Seymour Duncan’s best-selling Basslines pickup for a reason: it takes the classic P-Bass growl and adds real weight and push behind it. The secret is in the poles — ¼” diameter alnico 5 rod magnets instead of the standard skinny ones, which widens the magnetic window and pulls more low-mid and midrange out of the string. The result is a fatter, more aggressive voice with the output to match, and a B string that finally sits in the mix with authority instead of getting buried.
- Built for players who dig in — rock, metal, and hard-driving live gigs are where this pickup shines, though plenty of engineers reach for it in the studio too
- ¼” diameter alnico 5 rod magnets for expanded frequency response and higher output
- Forbon flatwork and vacuum wax potting keep things quiet on stage, no squeal even at high gain
- Direct drop-in for any American Standard Precision Bass — no routing, no modifications
- Hand-built in Santa Barbara, CA
- Ships with black covers
If you play a 5-string P-Bass and want the low B to punch as hard as the rest of the strings, this is the pickup that gets you there.
