Introduction

Setup
Before playing your new Jackson JS Series Spectra Bass JS2, follow these steps for initial setup.
1. Unboxing and Initial Inspection
Carefully remove the bass from its packaging. Inspect the instrument for any visible damage that may have occurred during shipping. Check the neck, body, hardware, and electronics.

2. Tuning the Instrument
The bass should be tuned to standard EADG (E-string lowest pitch, G-string highest pitch). Use an electronic tuner for accuracy. Turn the tuning pegs slowly to bring each string to the correct pitch. New strings may require frequent re-tuning until they stretch and settle.
- E-string: Thickest string, lowest pitch.
- A-string: Second thickest string.
- D-string: Third thickest string.
- G-string: Thinnest string, highest pitch.
Operating
Understanding the controls of your Spectra Bass JS2 is crucial for shaping your sound.
Controls Overview

Figure 3: Detail of the control knobs on the Jackson JS Series Spectra Bass JS2, including volume, blend, and tone controls.
- Volume Knob: Controls the overall output level of the bass. Turn clockwise to increase volume, counter-clockwise to decrease.
- Blend Knob: Mixes the output of the P-style (neck) and J-style (bridge) pickups. Rotate to favor one pickup over the other, or set in the middle for an even blend.
- Tone Knob: Adjusts the treble frequencies. Turn clockwise for brighter tones, counter-clockwise for warmer, darker tones.
- Active P/J Pickups: The bass features active pickups, which require a 9V battery (typically located in a compartment on the back of the body). Active electronics provide a higher output and more tonal shaping options. Replace the battery when the sound becomes weak or distorted.
Playing the Bass
Connect your bass to an amplifier using a standard instrument cable. Adjust the amplifier's settings to your preference. Experiment with the bass's controls to find your desired sound. Practice regularly to develop your playing technique.
Maintenance
Proper maintenance will preserve the playability and appearance of your bass guitar.
Cleaning
After each use, wipe down the strings and body with a clean, soft cloth to remove sweat and oils. For the body, use a guitar-specific polish occasionally. For the fretboard, use a lemon oil or fretboard conditioner to prevent drying and cracking, especially for laurel wood fretboards.
String Replacement
Strings should be replaced regularly, depending on usage, as old strings can lose their tone and intonation. Replace one string at a time to maintain neck tension. Use nickel plated steel strings with gauges appropriate for bass guitars (.045-.105 Gauges are standard).
Storage
Store your bass in a guitar case or gig bag when not in use to protect it from dust, humidity changes, and physical damage. Avoid exposing the instrument to extreme temperatures or sudden changes in humidity.
Troubleshooting
Here are some common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or weak sound | Dead battery (active pickups), faulty cable, amplifier off, volume knob down. | Replace 9V battery, check cable connections, turn on amplifier, increase volume. |
| Buzzing or Fret Noise | Improper setup (string action too low), worn frets, faulty grounding. | Adjust bridge saddle height, check neck relief, consult a qualified technician for fret work or electronics. |
| Poor Intonation | Bridge saddles not correctly set, old strings. | Adjust bridge saddle position for each string, replace strings. |
