Introduction
This manual provides essential information for the setup, operation, and maintenance of your Sterling by Music Man S.U.B. Series Ray5 StingRay Bass. Designed for excellent playability and clear low-end tone, the Ray5 features an active humbucking pickup and a 2-band EQ. Please read this manual thoroughly to ensure proper use and longevity of your instrument.
Setup
1. Initial Inspection
Upon unboxing, carefully inspect your bass for any signs of damage. Ensure all components are securely attached. The instrument is typically set up at the factory, but minor adjustments may be needed due to shipping or environmental changes.
2. Stringing and Tuning
The Ray5 is a 5-string bass. Ensure strings are correctly seated in the bridge and wound properly around the tuning pegs. Tune the bass to standard tuning: B-E-A-D-G (from lowest to highest string).

3. Action and Intonation Adjustment
The string action (height above the fretboard) and intonation (accuracy of notes across the fretboard) are crucial for playability and tone. These adjustments are typically made at the bridge saddles and truss rod. For optimal performance, especially if you are new to bass setup, it is recommended to have these adjustments performed by a qualified guitar technician.
4. Active Electronics and Battery
The Ray5 features active electronics, requiring a 9V battery for operation. The battery compartment is located on the back of the bass. Ensure a fresh battery is installed before use to guarantee proper function of the humbucking pickup and 2-band EQ.

5. Connecting to an Amplifier
Connect your bass to an amplifier using a standard 1/4-inch instrument cable. Ensure the amplifier is turned off or at a low volume before connecting or disconnecting the cable to prevent damage to your equipment.
Operating the Ray5 Bass
1. Controls Overview
The Ray5 is equipped with a single humbucking pickup and an active 2-band equalizer for versatile tone shaping. The controls typically include:
- Volume Knob: Controls the overall output level of the bass.
- Treble Knob: Boosts or cuts high frequencies.
- Bass Knob: Boosts or cuts low frequencies.

2. Tone Shaping
Experiment with the Treble and Bass knobs to achieve your desired sound. Boosting the bass can add warmth and depth, while boosting the treble can enhance clarity and attack. Adjusting these controls in conjunction with your amplifier settings will allow for a wide range of tonal possibilities.
Maintenance
1. Cleaning
- Body: Wipe the body with a soft, lint-free cloth after each use to remove sweat and fingerprints. For a deeper clean, use a guitar-specific polish.
- Fretboard: Periodically clean the fretboard to remove grime. For maple fretboards, a damp cloth can be used. For rosewood or ebony, use a specialized fretboard conditioner.
- Strings: Wipe down strings after playing to extend their life and maintain tone.
2. String Replacement
Replace strings regularly to maintain optimal tone and playability. When replacing, change one string at a time to maintain neck tension. Use strings of the same gauge and type to avoid significant setup changes.
3. Hardware Care
Keep all hardware (tuners, bridge, knobs) clean and free of corrosion. A light application of a non-abrasive cleaner can be used if necessary. Ensure all screws are snug, but do not overtighten.
4. Battery Replacement
When the sound becomes weak or distorted, it is likely time to replace the 9V battery for the active electronics. Open the battery compartment on the back of the bass and insert a fresh battery, observing polarity.

Troubleshooting
- No Sound: Check cable connections, amplifier power, and ensure a fresh 9V battery is installed in the bass.
- Buzzing Strings: This can be caused by low action, uneven frets, or improper neck relief. A truss rod adjustment or bridge saddle adjustment may be needed. Professional setup is recommended.
- Poor Intonation: If notes are out of tune higher up the neck, intonation adjustment at the bridge saddles is required.
- Weak or Distorted Sound: Replace the 9V battery. If the issue persists, consult a qualified technician.
