Assembly Instructions
The body and neck have been pre-treated with a pore filler. This finish is suitable for varnishing but may be unfavorable for staining, potentially requiring re-sanding if a stained finish is desired.
- Body Preparation (Optional Finishing):
If you wish to paint or stain your guitar, prepare the body and neck surfaces. The existing pore filler is suitable for varnish. For staining, light re-sanding may be necessary to ensure proper stain absorption. Follow the instructions of your chosen finishing product carefully.
- Install Tuning Machines:
Attach the tuning machines to the headstock. Ensure they are aligned correctly before tightening any screws. Some kits may require drilling pilot holes for the screws.
- Attach the Neck:
Carefully align the neck with the neck pocket on the body. Insert the neck plate and secure the neck to the body using the provided screws. Do not overtighten.
- Install Bridge and Tailpiece:
Mount the bridge and tailpiece hardware onto the body. Ensure proper alignment for string path and intonation. Refer to diagrams if available with your specific kit.
- Install Pickups and Controls:
Mount the P90 pickups into the pickguard. Install the volume and tone potentiometers, and the output jack. Follow the provided wiring diagram (if included) or a standard P90 wiring diagram for two pickups, two tone, two volume, and a 3-way switch (if applicable, though the image suggests a simpler setup with two pots and a switch on the pickguard). Solder all connections carefully, ensuring good contact and insulation.
- Attach Pickguard:
Once the electronics are wired and tested (a quick continuity check can be useful), carefully place the pickguard onto the body and secure it with screws.
- Install Strap Buttons:
Attach the strap buttons to the designated locations on the body. Pre-drill pilot holes to prevent wood splitting.
- String the Guitar:
Install the guitar strings. Start with the lowest E string and work your way up. Stretch the strings gently to help them settle.
- Initial Setup:
After stringing, perform an initial setup. This includes tuning the guitar, adjusting the string action (height) at the bridge, checking the neck relief (truss rod adjustment), and setting the intonation. Numerous online resources and guides are available for detailed guitar setup procedures.
Operating Your Guitar
Once assembled and set up, your Harley Benton JA Electric Guitar is ready to play.
- Tuning: Use an electronic tuner to accurately tune your guitar to standard EADGBe or your preferred tuning.
- Connecting to an Amplifier: Use a standard 1/4-inch instrument cable to connect the guitar's output jack to your amplifier's input.
- Volume Control: Adjust the master volume knob on the guitar to control the overall output level.
- Tone Control: Use the tone knob(s) to shape the treble response of your pickups. Turning it down will produce a warmer, darker sound.
- Pickup Selector: If your kit includes a pickup selector switch, use it to choose between the neck pickup (warmer tone), bridge pickup (brighter, more aggressive tone), or both pickups combined.
Maintenance
Regular maintenance will ensure your guitar remains in optimal playing condition and prolong its lifespan.
- Cleaning: Wipe down the body, neck, and strings with a soft, lint-free cloth after each use to remove sweat and grime. Use guitar-specific cleaning products for deeper cleaning or polishing.
- String Replacement: Change strings regularly, typically every 1-3 months depending on playing frequency. Old strings lose their tone and intonation.
- Fretboard Care: For maple fretboards, occasional cleaning with a damp cloth is usually sufficient. Avoid excessive moisture.
- Hardware Check: Periodically check all screws and nuts (tuners, bridge, strap buttons) for tightness. Do not overtighten.
- Humidity Control: Store your guitar in an environment with stable temperature and humidity to prevent wood warping or cracking.
Troubleshooting
Here are some common issues and their potential solutions:
- No Sound:
- Check cable connections (guitar to amp).
- Ensure amplifier is on and volume is up.
- Check guitar's volume knob.
- Inspect wiring for loose or broken solder joints.
- Test with a different cable or amplifier.
- Buzzing Frets:
- String action might be too low. Adjust bridge height.
- Neck relief might be incorrect. Adjust the truss rod (consult a professional if unsure).
- Uneven frets. This may require professional fret leveling.
- Poor Intonation:
- Strings may be old. Replace them.
- Bridge saddles need adjustment. Tune the open string, then check the 12th fret harmonic and fretted note. Adjust the saddle forward or backward until they match.
- Scratchy Pots/Controls:
- Dust or dirt inside the potentiometers. Use a contact cleaner designed for electronics.
