What You Need to Know Before You Start

Changing a guitar pickup takes about 30 minutes to an hour and requires only a screwdriver, a soldering iron, and solder. You do not need to take your guitar to a repair shop — the job is straightforward enough for a first-timer, and the hardest part is usually unsoldering the old wires rather than the physical removal itself.

The pickup sits under the strings in the body cavity or pickguard and connects to your guitar's electronics through two thin wires. When you replace it, you are disconnecting those old wires, removing the pickup, installing the new one in the same spot, and soldering the wires back. The new pickup will drop into the existing mounting holes, so there is no drilling or permanent modification to your guitar.

Key Takeaways

  • You will need a soldering iron, solder, a screwdriver, and a desoldering pump or solder wick to remove the old wires cleanly.
  • Take a photo of the wire connections before you desolder anything, because the color coding varies by manufacturer and you will need to match them exactly on the new pickup.
  • The pickup itself is held in place by screws or springs — remove these first, then carefully pull the pickup out of the cavity.
  • New pickups come with wires already attached, so you only solder the two connections at the output jack or control cavity, not inside the pickup itself.
  • Test your guitar with an amplifier before you close up the body, because finding a cold solder joint after reassembly means opening everything again.

Gather Your Tools and Materials

Before you open your guitar, lay out a soldering iron (25 to 40 watts is standard), rosin-core solder (60/40 or 63/37 tin-to-lead ratio), a desoldering pump or solder wick, a small screwdriver that fits your pickup mounting screws, and needle-nose pliers. You will also want a small container or tape to keep screws organized — guitar cavities are dark, and a screw rolling into the body cavity is a frustrating detour.

Have your new pickup on hand before you start, and check that it comes with wires attached. Most aftermarket pickups do; if yours does not, you will need to solder the coil wires to the output leads before installation, which is a separate and more delicate task. Keep the old pickup nearby until you have the new one working — if something goes wrong, you can always reinstall the original while you troubleshoot.

Document the Wire Connections

Open your guitar's control cavity or remove the pickguard to expose the pickup wires. Before you touch anything, take a clear photo of how the wires connect to the output jack or control cavity. The two wires from your pickup — usually one black and one white, though colors vary — connect to specific terminals, and reversing them will flip the phase of the pickup, which changes the tone and can cause problems if you have two pickups.

If the wires are soldered to a terminal block or directly to the jack, note which wire goes where. Some guitars use a connector block that unplugs instead of solder connections; if yours does, you can skip the soldering step entirely and straightforward unplug the old pickup and plug in the new one. Check your guitar's wiring diagram online if you are unsure — search for your model and "wiring diagram" to find a labeled schematic.

Remove the Old Pickup

Heat your soldering iron for two to three minutes. Once it is hot, use the desoldering pump or solder wick to remove the solder from the two wire connections. Place the pump or wick against the solder joint, explore the iron tip to heat it, and pull away — the solder will flow into the wick or pump. Repeat until the joint is clean and the wire pulls free. Work slowly; rushing this step can damage the jack or control cavity.

Once both wires are free, locate the pickup mounting screws or springs. Most pickups are held in place by two screws on either side, or by springs that tension the pickup against the body. Remove these fasteners and set them aside in your screw container. Gently pull the old pickup straight out of the cavity — it should slide out without resistance. If it does not, check that all fasteners are removed and that no wires are still soldered.

Install the New Pickup

Slide the new pickup into the cavity, aligning it with the mounting holes. The pickup should sit at the same height and distance from the strings as the old one did. Once it is positioned, reinstall the mounting screws or springs and tighten them finger-tight — do not over-tighten, as this can crack the pickup or warp the mounting plate.

Check the pickup height by plucking a string and listening for buzzing or loss of tone. If the pickup is too close to the strings, it can cause magnetic interference and a thin, weak sound. If it is too far away, the signal will be weak. Most pickups sit about 2 to 3 millimeters below the strings at the treble side and slightly higher at the bass side, though this varies by pickup type. Adjust the screws or springs until the tone sounds balanced and clear.

Solder the Wires and Test

Route the new pickup wires to the output jack or control cavity, following the same path the old wires took. Tin the iron tip with a small amount of solder, then heat the terminal where the first wire will connect. Touch the solder to the joint (not directly to the iron) and let it flow around the connection. The joint should look shiny and smooth, not dull or blobby. A dull joint is a cold solder and will cause crackling or signal loss.

Repeat for the second wire, matching the colors to your photo from earlier. Once both connections are cool, plug your guitar into an amplifier and test each string. Play loudly and listen for crackling, buzzing, or weak signal. If everything sounds clean and strong, you are done. If you hear crackling, one of the solder joints is cold — reheat it and add a tiny amount of fresh solder. If the signal is very weak or absent, check that the wires are connected to the correct terminals by comparing to your photo.

Close Up Your Guitar and Adjust as Needed

Once the pickup is working, reinstall the pickguard or close the control cavity. If your guitar has a pickguard, align the screw holes carefully and tighten the screws evenly to avoid warping the guard. Take your time here — a pickguard that is not seated properly can rattle or shift during playing.

Play your guitar for a few minutes to make sure everything is stable. Check that the tone knobs and volume control work smoothly and that there is no crackling when you turn them. If you notice any issues, open the cavity again and inspect the solder joints and wire routing. Most problems at this stage are loose connections or wires touching the cavity walls, both of which are quick fixes.

Frequently Asked Questions

Do I need to solder, or can I use a connector block?

If your guitar already has a connector block (a plastic or metal block with terminals that wires plug into), you can unplug the old pickup and plug in the new one without soldering. Check inside your control cavity — if you see a block with two wires plugged into it, you have a connector. If the wires are soldered directly to the jack, you will need to solder the new ones.

What if I reverse the wires by accident?

Reversing the wires flips the phase of the pickup, which changes the tone and can cause phase cancellation if you have two pickups. The guitar will still work, but it may sound thin or weak. straightforward desolder the wires, swap them, and resolder. There is no risk of damage — phase reversal is not harmful, just undesirable.

How do I know if my solder joint is good?

A good solder joint looks shiny and smooth, like a small cone of metal around the connection. A cold joint looks dull, grainy, or blobby and will cause crackling or signal loss. If you are unsure, reheat the joint and add a tiny amount of fresh solder — a good joint will flow smoothly and become shiny.

Can I change a pickup on a semi-hollow or hollow-body guitar?

Yes, but access is more limited. Semi-hollow and hollow-body guitars have smaller cavities, and you may need to remove the pickup through the f-hole or access port. Check your guitar's manual or search for your model online to see the recommended removal method. The soldering and installation steps are the same.

What if the new pickup does not fit in the mounting holes?

Pickup mounting holes vary slightly by manufacturer. If the new pickup does not align with the old holes, you can drill new holes or use shims (thin spacers) to adjust the position. Most aftermarket pickups come with multiple mounting options, so check the documentation. If you are uncomfortable drilling, a repair shop can do this in minutes.
