Setup

  1. Unpacking: Carefully remove the bass and all accessories from the packaging. Inspect for any signs of damage during transit.
  2. Attaching the Strap: Securely attach the guitar strap to the strap buttons located on the body of the bass. The Dunlop dual-locking strap buttons provide enhanced security.
  3. Connecting the Cable: Insert one end of the included guitar cable into the output jack on the bass. Connect the other end to your amplifier or audio interface.
  4. Tuning the Bass:
    • Turn on the electronic tuner.
    • Pluck each string individually. The tuner will display the note being played.
    • Adjust the tuning pegs (machine heads) on the headstock until each string is in tune. Standard bass tuning is E-A-D-G (from thickest to thinnest string).

Controls:

  • Volume Control: Adjusts the overall output level of the bass.
  • Blend Control: Mixes the output between the neck and bridge pickups. Turn towards the neck for a warmer tone, towards the bridge for a brighter, more articulate sound.
  • 3-Band EQ (Active Only): Provides control over Bass, Mid, and Treble frequencies when the bass is in active mode.
  • Two-Way Toggle Switch (Active/Passive): Switches between active (powered by battery, allowing EQ control) and passive (no battery required, EQ bypassed) modes.
  • Three-Way Toggle Switch (Variable Mid-Frequency): Selects different mid-range frequencies for the EQ, allowing for fine-tuning of your tone.

Playing:

Once tuned and connected, you can begin playing. Experiment with the control knobs to find your desired tone. The ergonomic design of the Spectra Bass body ensures comfortable playing whether seated or standing.

Maintenance

Proper maintenance will ensure the longevity and optimal performance of your bass.

  • Cleaning: After each use, wipe down the strings, fretboard, and body with a clean, soft cloth to remove sweat and dirt. For the body, a guitar-specific polish can be used periodically.
  • String Replacement: Strings should be replaced regularly, depending on usage, to maintain optimal tone and playability. Refer to general bass guitar string replacement guides for detailed steps. The Jackson Single-String hardtail bridge simplifies individual string changes.
  • Fretboard Care: Periodically clean and condition the caramelized jatoba fretboard with a suitable fretboard oil to prevent drying and cracking.
  • Battery Replacement: If using the active electronics, the 9V battery will eventually need replacement. Access the battery compartment on the back of the bass.
  • Storage: Store the bass in a climate-controlled environment, ideally in a gig bag or hard case, to protect it from extreme temperature changes and humidity fluctuations.

Troubleshooting

Here are solutions to common issues you might encounter:

  • No Sound:
    • Check if the amplifier is on and volume is up.
    • Ensure the guitar cable is securely connected at both ends.
    • If in active mode, check the 9V battery. Replace if necessary.
    • Test with a different cable or amplifier if possible.
  • Buzzing/Humming Noise:
    • Ensure proper grounding of your amplifier and power outlets.
    • Check for loose connections in the cable or input jack.
    • If the buzzing is only when not touching strings, it might be normal single-coil hum (though Nordstrand pickups are designed to minimize this).
  • Poor Tuning Stability:
    • Ensure strings are properly stretched after installation.
    • Check for worn-out strings; replace if old or corroded.
    • Verify that the tuning pegs are not loose.
