Josefina Hand-Wound Fender Custom Shop Troposphere Single Coil Pickups - Loaded Pickguard

The Ultimate Upgrade – Hand-Wound Josefina Troposphere Pickups

If you're looking for that next-level tone, these hand wound Troposphere pickups deliver. Able to transform and Strat into a true tone machine.

Josefina Campos, Fender's Master Pickup Winder, lives up to all the hype. She is the go-to winder for Fender’s most exclusive Master Builds and Artist Series models. These Troposphere pickups capture that legendary, vintage Fender sound, delivering a perfectly balanced tone with sparkle, clarity, and rich warmth.

Custom Wiring for a Perfectly Calibrated Set:

To ensure a smoother, more balanced output, I’ve personally wired these pickups with a custom touch: I flipped the bridge pickup to the neck position for a more calibrated transition. The result is a more consistent, sweet-sounding neck and middle position while keeping the bridge punchy and articulate.

These pickups excel in everything from glassy cleans to dynamic overdrive. Whether you're channeling classic Strat tones or crafting your own signature sound, this set is a serious upgrade.

Resistance Readings:

• Neck: 5.34 ohms
• Middle: 5.65 ohms
• Bridge: 5.57 ohms

Plug and Play! Ready to be dropped in your favorite Strat.

I personally wired this set with the upmost attention to detail; using the same CTS Audio 10% Taper pots used by FCS, mounted to an American Vintage mint green pickguard with FCS covers and knobs.

*Seller's Note*

At Rock Island Line, boutique and premium is what we do best. Every part is personally sourced from trusted licensed shops or carefully vetted private sellers, and parted out from new or mint-condition, fully assembled guitars. We take our time with every detail, right down to the last screw. That means no stripped screw holes, overtightened truss rods, unexpected modifications, or surprises—unless explicitly noted.

What you’re getting is a plug-and-play piece from a working guitar—inspected, played, and professionally disassembled.

We believe integrity and quality matter. When something’s built to last and handled with care, it becomes more than just a component—it becomes part of the story.

Our goal is to provide heirloom-worthy pieces that feel right, perform beautifully, and bring out the best in your prized instrument.

Have a question or a request? I’m happy to connect by call, text, or FaceTime. We live by the golden rule: treat others how you want to be treated.

Thank you very much—we look forward to earning your business and trust.
