Fitting Instructions
Removal
- Find somewhere safe, dry and secure to place your Aria Pro II TA Classic, TA-40, TA50 and TA-60 Hollowbody Guitar while you work on it.
- Undo the screws that hold the scratch plate to the body (if your guitar has one) and remove scratch plate.
- If you are not changing the pickups, although this will be the time to do it if you are, you can leave the strings on, which will make testing easy later.
- Undo the nut for the jack socket.
- Remove the control knobs x 4 and the switch cap.
- Remove the 4 x pot nuts and dress washers and the nut for the switch.
- You now need to bring what is inside to the outside. Its best to use a protective cloth to stop the guitar surface getting scratched.
Replacement
- Working on the now external old harness, cut the 1 x bridge ground wire at the pot leaving the wires as long as possible.
- Cut the pickup wires leaving the wires as long as possible.
- You should now be able to remove the harness away from the guitar.
- At this point you may want to clean pot holes from where the old pots have been.
- You will need to check the size of the holes for the pots as on some guitars they are drilled small for cheap electrical components. If they are small, the best way to enlarge them to 10mm to fit CTS pots, is to carefully use a round file or drill. (take your time as the paint can chip).
- You are now ready to fit the new harness.
- From here, everything is in reverse using the wiring diagram below.
- Place the new harness on top of the guitar.
- Solder the 1 x ground bridge wire to the back of the new tone pot (refer to wiring diagram).
- Solder the 2 pickup wires to the new pots (refer to wiring diagram).
- Once this is done, you should test to make sure everything is working. Simply plug into an amp and strum a string if the strings are fitted or use a Multimeter.
- You will now need to thread everything back into the guitar to the correct holes. Start with the jack socket, you may need a bit of fishing line to help you feed the jack into place, now everything else will follow. Take you time with this part so you don’t damage any of the components or paint work.
- Re-fit the control knobs and the switch cap.
- Fit the pickguard back into place and you are ready to go.
Tools & Equipment
- Philips (Cross head) Screwdriver / Flat headed screwdriver on some models.
- Small adjustable spanner/wrench.
- Good quality soldering iron.
- Wire cutters.
- Masking tape for keeping things in place or out the way while working.
- Pair of long nose pliers or strong pointed tweezers.
- Fishing line or thin cord to pull through the components.
- A bit of patience!
Tips
- Gently feed the components through the F sound hole, take you time.
- When soldering the wires to the back of a pot, do not overheat / cook the pot.
- Keep wires tidy and neat and make sure all components are grounded.
