TIP # 1: CHOOSING THE CORRECT SOLDER
Using the right solder is key to making sure you get the job done right. Ideally, the best solder to use is a lead-based solder with a rosin core. Lead-based solder with a rosin core will secure a reliable electrical connection and flow nicely. We use the Kester® brand of solder, and you can usually find Kester® Solder at your local hardware store.
Don't have the Kester Solder? That's okay! Most solder will work well for installing pickups. One type of solder is a pain to work with, though - Lead-Free Solder. This solder does not flow and is prone to cold solder joints. Avoid this if you can.
TIP # 2: CHOOSE THE RIGHT SOLDERING IRON
Use a soldering pencil - not a gun! Soldering guns are unwieldy and produce a magnetic field around them. This magnetic field can demagnetize your pickups during installation - a huge bummer.
TIP # 3: MAKE THE RIGHT CONNECTION
The best connection you can make when soldering is a "Mechanical Connection". A Mechanical Connection features a "kink" in the wire before the solder is applied. When connected properly, a Mechanical Connection is basically fail-proof!

TIP # 4: PRE-TIN
Pre-tinning your connections is one of the most game-changing tips we can offer. It's the difference between a clean, pretty, and effective solder joint and a messy "cold" one. To pre-tin your connections, simply apply solder to both elements you want to connect before soldering them together.
For example, if you were soldering a 5-Way switch, you would pre-tin the terminal of the switch and pre-tin the pickup's wire separately. Then, all you would have to do is join the two and apply heat from your soldering pencil, and voila! You have a beautiful, clean solder joint. Pre-tinning coats each surface with solder and burns away any impurities on each surface to provide a clean and effective solder joint.
TIP # 5: PROTECT YOURSELF
Soldering can be dangerous. Use proper eye protection and wash your hands after soldering if using lead-based solder - it's poisonous!
