Determine whether your P-90 equipped neck pickup is reverse wound (most common) or wound in the same direction as the bridge pickup.

If your P-90 equipped guitar has no buzz with the pickup selector switch in the middle position then you need a Dual- Coil P-90 BzzzzKill.

If it has the same amount of buzz no mater where the pickup selector switch is then you need a Single-Coil P-90 BzzzzKill.

Turn your guitar’s volumes all the way off. Only turn them up briefly when testing and make sure they are off again before making any solder connections.

Unscrew the control cavity plate.

If your P-90 equipped guitar has the same amount of buzz no mater where the pickup selector switch is then you need a Single-Coil P-90 BzzzzKill.

Perform the P-90 pickup mod as shown in the video. Your pickup now has a dedicated positive and negative wire and a separate shield. If your pickup already has this wiring harness, then no mod is necessary.

Positive pickup coil wire goes to the volume pot terminal for each pickup. Negative coil wires for both pickups get connected together.

Connect one side of the BzzzzKill coil to ground using a alligator clip. Connect the other side of the BzzzzKill to the connected negative pickup wires using a alligator clip.

Turn the volume up and use high gain to evaluate the buzz. Reverse the BzzzzKill connections to find the quietest orientation. This is the correct orientation.

Solder the BzzzzKill lead to the joined pickup wires and apply heat-shrink. Solder the other BzzzzKill lead to ground, typically the back of the volume pot.

Note: Keep solder joints low and flush on the pot to avoid clearance issues. Position any capacitors below the plane of the pot base, as shown in the video.

If your P-90 equipped guitar has no buzz with the pickup selector switch in the middle position then you need a Dual-Coil P-90 BzzzzKill.

Perform the P-90 pickup mod as shown in the video. Your pickup now has a dedicated positive and negative wire and a separate shield. If your pickup already has this wiring harness, then no mod is necessary.

Positive pickup coil wire goes to the volume pot terminal for each pickup. Keep the negative pickup wires separated. Each pickup connects to its own BzzzzKill coil.

Using alligator clips, connect the black wire from the neck pickup to one BzzzzKill coil and connect the other lead to ground. Turn up the volume with high gain and reverse the connections to find the quietest orientation. Solder once confirmed and heat shrink.

Repeat this process for the bridge pickup using the second BzzzzKill coil.

You should now have both pickup leads soldered to the BzzzzKill, with one remaining lead from each coil. Solder both remaining leads to ground usually on the back of the volume pot. Ensure the pots are in the off position.

Perform a bench test to confirm everything is working, then gently arrange the wires so they sit beside the BzzzzKill without being pinched.

Position the BzzzzKill in the control cavity using some packing to raise it slightly higher than the control plate

Remove the red backing from the mounting tape and press firmly to secure the BzzzzKill to the back of the control plate as shown in the video.

You may still hear some buzz while the guitar is disassembled. The BzzzzKill reaches full performance only after the guitar is fully assembled, restrung, and hanging from your body.

After installing BzzzzKill, your P-90’s true single-coil voice will shine through without the buzz. You may need to adjust your guitar’s tone controls, amp’s tone controls, amp’s EQ or effects settings to get your perfect sound. Think of it this way: by removing the buzz, you’re unmasking your guitar’s unique voice and letting the pristine sound of true single-coil pickups shine through.

Your P-90’s now sound the way they were always meant to!
