HFS, Dragon II, 57/08 or 85/15? Figuring Out Which Pickups Are in a Used PRS

Short answer: PRS has used close to a dozen humbucker designs since the '80s, and the year a guitar was built only gets you partway to knowing which set it has. The date-series names (57/08, 59/09, 58/15, 85/15) are easy to decode once you know the trick. But the only reliable way to know what's in a specific used PRS is the paperwork, the pickups themselves, or PRS customer service with the serial number. I've had a 2003 Custom 24 on the bench whose hangtag contradicts what most people would guess for that year. That's why I never price a PRS off an assumption.

How to read the numbers in a PRS pickup name

PRS's date-series names follow one rule. The first number is the design reference and the second is the year PRS released the pickup. PRS spells it out for the 57/08: the name pairs "1957 humbuckers" with 2008, the year it came out. The rest follow the same pattern:

• 57/08 – 1957-style humbuckers, introduced 2008. Alnico 2. PRS says it secured wire made on the same machine that supplied 1950s pickups and winds these in-house. For years you could only get them in a guitar; PRS began selling them separately in 2017.
• 59/09 – introduced 2009. Alnico 2, voiced for clarity with a touch of brightness in the bridge.
• 58/15 – introduced 2015 on vintage-leaning models like the McCarty and P245. The 58/15 LT ("Low Turns") arrived on the McCarty 594. Paul Reed Smith has said that, unusually, the treble and bass versions are the same pickup and the bridge isn't wound hotter.
• 85/15 – also 2015, first on the 30th Anniversary Custom 24. The "85" points back to PRS's original 1985 pickups. Paul described the goal as advancing both modern and vintage sounds and "greatly refining single-coil sounds all out of hum-canceling pickups." It became the modern PRS voice on the Custom 24 and CE 24.

The names that don't follow the date code

Older PRS pickups and signature models use plain names, and these are the ones that trip up most buyers of '90s and 2000s guitars:

• HFS and Vintage Bass. HFS stands for "Hot, Fat, Screams," which tells you what it's for. It's a hot, ceramic-magnet bridge pickup, usually paired with the alnico Vintage Bass in the neck. PRS's own model history puts the HFS/Vintage Bass pairing on the Custom by late 1991. That set is a big part of what people mean by "the '90s PRS sound." Some players love the clarity and push. Others call it harsh or "dull city," sometimes in the same thread. Both reactions are fair, and a lot depends on the amp.
• Dragon II. An alnico humbucker with a strong following among players who want a hot-PAF flavor. It's often cited as standard on the CE 22 and turns up on plenty of Custom 22s and Customs from that era.
• Model-named sets like the McCarty or DGT pickups were voiced for one specific guitar.

Two newer terms cause even more confusion. TCI stands for "Tuned Capacitance and Inductance." It's a process, not a separate pickup family: PRS measures a pickup it likes and then builds production pickups to match its capacitance and inductance. From around 2019–2020 you'll see "TCI" attached to 85/15s, 58/15 LTs and others. An "S" on the end (85/15 "S," 58/15 "S," TCI "S") marks the version made for SE and S2 guitars. It shares a name with the Core pickup but it's a different pickup, and owners who've compared them side by side say you can hear it.

Why the year alone won't tell you

This is the part most buyer's guides skip. A rule of thumb like "early-2000s Custom 24 = HFS/Vintage Bass" is often right. But PRS offered pickup options, dealers placed orders to their own spec, and special runs changed things. On top of that, twenty years of owners have had plenty of time to swap parts.

Here's a real example from our bench. The 2003 Custom 24 10-Top in Whale Blue still has its original hangtag, and the factory filled in Dragon 2 for both pickups. Most people would guess HFS/Vintage Bass for a 2003 Custom 24. In the listing I said the pickups are believed original but that I hadn't pulled them to check the markings. The tag tells you what left the factory. It doesn't prove the same pickups are in there today. Those are two separate questions, and a careful buyer asks both.

The 2023 CE 24 Satin Nitro in Gold Top is the reverse case. Going by the model name, you'd expect 85/15s. This one came from a dealer-exclusive special run with an ebony board and covered 57/08s. On my bench it sounded far closer to vintage PAF territory than a standard CE: warm and open rather than hot. If you'd assumed "CE = 85/15" and compared it to one, you'd have no idea why they sound so different.

How I actually identify the pickups in a used PRS

1. Read the paperwork first. Older hangtags have Treble and Bass lines, like the one above. Wood Library and special-order guitars usually have tags or spec sheets that record the build.
2. Email PRS with the serial. PRS customer service will look up how a guitar shipped. Players on the PRS forum report getting build details, pickups included, from the serial number alone. Several of our listings note specs "confirmed by PRS" for exactly this reason.
3. Look at what's visible, but don't trust it on its own. Covers, bobbin colors and pickup rings can narrow things down, but they aren't proof. The date-series and Dragon families have both appeared covered and uncovered.
4. Pull a pickup if it matters. The baseplate will have markings or a label. On a guitar where originality drives the price, this is worth ten minutes and a screwdriver.
5. Trust your ears last. Pickup height, pots and the amp shape the sound so much that "it sounds like 85/15s" isn't identification.

The 2019 Custom 24 Wood Library in Yellow Tiger is a good example of step 3. The neck pickup is covered and the bridge isn't. That pairing works well tonally: warm and open in the neck, punchy and articulate in the bridge. But I couldn't confirm both pickups are original, so the listing says "unknown." A mismatched look isn't proof of a swap on a Wood Library guitar, where odd specs are the whole point. It is a reason to check the paperwork or ask PRS.

Does it matter which set you get?

For playing, less than the internet suggests. For value, more. My take: buy the neck, the top and the guitar's feel. Treat the pickups as the most reversible part of the guitar. If a '90s Custom feels perfect but the HFS is too spiky for you, or a 2016 Custom 24's 85/15s sound too modern, there's a fix that costs a lot less than the wrong guitar. That's why I'd much rather see a player swap pickups than walk away from a great instrument.

The catch is resale. Collectors and serious PRS buyers pay for original, documented guitars. If you swap, keep the originals and put them in the case. An original-pickup PRS with its hangtag is an easier sale than one with a question mark. If you already have one with original pickups and paperwork, that documentation belongs in the conversation when you get a cash offer.

FAQ

What does 85/15 mean on a PRS?

It follows PRS's date-series naming. The "85" refers back to the company's original 1985 pickups, and "15" is the year it launched, 2015, on the 30th Anniversary Custom 24.

Are 58/15 and 85/15 the same pickup with different names?

No. The 58/15 family is voiced toward late-'50s PAF-style humbuckers and suits vintage-leaning models like the McCarty 594. The 85/15 is PRS's more modern voice, with a hotter bridge and a design focused on convincing split sounds.

Is a PRS with TCI pickups better than an older one?

Not automatically. TCI is about consistency: every pickup built to match a target PRS measured and liked. It doesn't make an older, non-TCI set worse. Plenty of players still prefer 59/09s or Dragon IIs.

Are SE "S" pickups the same as Core PRS pickups?

No. The "S" versions are made for SE and S2 guitars. They share names and general voicing goals with the Core pickups, but they're separate pickups, and swapping to Core pickups is a common SE upgrade.
