Setup

1. Unpacking and Initial Inspection

• Carefully remove the guitar from its packaging.
• Inspect the guitar for any signs of shipping damage. If damage is found, contact your dealer immediately.
• Confirm all included accessories are present. Your guitar should come with a gig bag.

2. Tuning

Your 7-string guitar is typically tuned from low to high: B-E-A-D-G-B-E. Use a reliable electronic tuner for accurate tuning. The locking tuners on your guitar help maintain tuning stability.

1. Insert the string through the bridge.
2. Pull the string taut through the tuning machine post.
3. Tighten the locking mechanism on the tuner.
4. Tune the string to the desired pitch.

3. Stringing and Action

The guitar comes factory-strung with a specific gauge suitable for its design. When replacing strings, consider using a similar gauge to maintain optimal playability and intonation. The string action (height of strings above the fretboard) and intonation are factory-set. Significant adjustments should be performed by a qualified guitar technician to prevent damage and ensure proper setup.

Operating

1. Controls Overview

2. Pickup Selector Positions

• Position 1 (Bridge): Activates the bridge humbucker for a sharp, aggressive tone, ideal for lead playing and heavy riffs.
• Position 2 (Middle): Activates both the bridge and neck humbuckers for a fuller, balanced tone.
• Position 3 (Neck): Activates the neck humbucker for a warm, smooth tone, suitable for rhythm and clean passages.

3. Connecting to an Amplifier

To hear your guitar, connect it to an amplifier using a standard 1/4-inch instrument cable.

1. Ensure your amplifier is turned off or on standby.
2. Plug one end of the instrument cable into the guitar's output jack.
3. Plug the other end into the input jack of your amplifier.
4. Turn on your amplifier and adjust its volume and tone settings as desired.

Maintenance

1. Cleaning

• Body: Wipe the body with a soft, lint-free cloth after each use to remove sweat and fingerprints. For deeper cleaning, use a guitar-specific polish or cleaner sparingly.
• Neck and Fretboard: The ebony fretboard should be cleaned periodically. Use a soft cloth to wipe away grime. For accumulated dirt, a specialized fretboard cleaner or a small amount of lemon oil (specifically for unfinished fretboards) can be applied, then wiped clean. Avoid excessive moisture.
• Strings: Wipe strings with a clean cloth after playing to extend their life and maintain tone.

2. String Replacement

Strings should be replaced regularly, depending on playing frequency and personal preference. Old strings can lose their tone and intonation. When replacing, change one string at a time to maintain neck tension. Refer to the "Tuning" section for instructions on using the locking tuners.

3. Hardware Maintenance

Periodically check all screws and hardware for tightness. Avoid over-tightening. Lubricate moving parts of the bridge (if applicable) with a small amount of specialized lubricant if they become stiff.

4. Storage

Store your guitar in its gig bag or a hard case when not in use to protect it from dust, humidity changes, and physical damage. Avoid extreme temperatures and sudden changes in humidity, which can affect the wood.

Troubleshooting

• No Sound:
  • Check if the instrument cable is securely plugged into both the guitar and the amplifier.
  • Ensure the amplifier is turned on and not on standby, and its volume is up.
  • Verify the guitar's volume knob is turned up.
  • Test with a different cable or amplifier if possible to isolate the issue.
• Buzzing or Fret Noise:
  • This can be caused by low string action, uneven frets, or improper neck relief.
  • Minor adjustments to string height can be made, but for significant buzzing, a professional setup by a qualified technician is recommended.
• Tuning Instability:
  • New strings require stretching. Play the guitar for a while after stringing, and re-tune frequently.
  • Ensure strings are properly seated in the locking tuners and nut.
  • Extreme temperature or humidity changes can affect tuning.
• Weak or Intermittent Signal:
  • Check all cable connections.
  • Inspect the output jack for loose connections. This may require professional attention.
  • Ensure the pickup selector switch is fully engaged in a position.
