Introduction

This is a basic disassembly guide for an Ibanez GSA60 Gio series electric guitar. This will show you how to access all of the internal hardware and how to remove all other outside components not connected by wiring. All wiring will be left intact, as soldering is only required for replacing components. Steps for cleaning unsightly rust and corrosion using cheap, common household materials are included after the disassembly. The bulk of the required time is spent soaking rusted components in a solution to soften the rust; the disassembly portion should take no more than 1 hour.

If desired, lay a cloth or towel on the table to avoid scratching the table or the surface of the guitar. Put on safety glasses before beginning disassembly. Safety glasses should be worn when doing any project with parts under tension or caustic chemicals. To begin removing the strings, turn the first tuning peg clockwise. Keep tension in the string with your other hand. This makes removing the string easier.

  • Once the string has been unwound, pull the end of the string out of the hole in the tuning peg.

  • The free end of the string can be sharp. You may use pliers to remove the string to prevent pricking your fingertips.

At the bridge, push each string through the guitar. The end of the string will be pushed out of the back of the guitar. Grab the string and pull it completely through and out of the guitar body. It may be necessary to straighten out the previously wound up ends if they will not come through.

Flip the guitar up-side-down and locate the screws at the top of the body near the neck. Use a Phillips 2 Screwdriver to unscrew the screws. Both a screw and a spacer will be removed. Take note of the difference in screw sizes. The screws closer to the neck are 1 7/16" The screws farther from the neck are 1 3/4"

Carefully flip the guitar right-side-up. Locate the knobs on the front of the guitar to the right of the pickups. These cover the potentiometers (or pots), which control volume and tone. Using a flat object such as a pair of pliers, a flat head screwdriver, or a coin, carefully pry the knob up off of each pot. The knob may require a lot of force to remove.

Flip the guitar up-side-down and locate the electronics cavity. If the wires are zip-tied, use wire cutters to cut the tie. This will free up slack in the wires and make removal of later components easier. Take care to avoid cutting the wires when cutting the zip tie or when moving the wiring later.

  • Add 2 cups of distilled white vinegar (any vinegar will work) to a bowl.

  • Add 2 tbsp of salt to the vinegar and mix.

  • The salt lowers the pH of the vinegar, making it more acidic to dissolve rust more quickly.

  • Gloves are recommended to keep the vinegar solution off of your hands. Vinegar can ruin your guitar's finish, and the extra acidity may irritate sensitive skin.

Place a paper towel underneath each pickup to catch rust and keep it from falling into the guitar body. Using an abrasive pad, carefully rub off the heavy surface buildup of rust. Do not use a magnetic scrubber (steel wool), as the residue will be nearly impossible to completely remove from the poles.

  • You do not need to completely remove all rust from the pickups. The discolored look is a desirable feature, and many guitarists actually pay extra to have their pickups slightly "aged". Additionally, light rust has no effect on the performance of the pickups.

Use the abrasive scrubber to gently polish rust off of electrical components. Scrub gunk due to sweat and dead skin from the frets with a cotton swab. The edge of a guitar pick can also be used to loosen tough spots. Scrub gunk due to sweat and dead skin from the frets with a cotton swab.

This solution will be used to neutralize the vinegar to remove the odor and prevent damage to the guitar's finish. After 2 1/2 hours, the components are ready to be transferred from the vinegar solution. Fill a second bowl with 2 cups of water, add 2 tbsp of baking soda, and mix.

Use a cotton swab to apply the baking soda solution to the components previously treated with the vinegar solution. Soaking in the baking soda solution is not necessary, the reaction happens almost instantly. Use the abrasive scrubber to polish off the softened rust.
