Setup
Unpacking and Inspection
Carefully remove the bass from its packaging. Inspect the instrument for any signs of damage that may have occurred during shipping. Retain all packaging materials in case the instrument needs to be returned or transported.
Battery Installation
The StingRay HH RAY4HH requires one 9V alkaline battery for its active electronics. The battery compartment is located on the back of the bass. Ensure the battery is inserted with the correct polarity.
Tuning
Use a reliable electronic tuner to tune your bass. The standard tuning for a 4-string bass is E-A-D-G (from thickest to thinnest string).
Strap Attachment
Attach your bass strap securely to the strap buttons located on the body of the instrument. Ensure the strap is properly fastened before playing.
Operating
Controls Overview
The StingRay HH RAY4HH features a 2-band active preamp with three control knobs:
- Volume: Controls the overall output level of the bass.
- Treble: Adjusts the high-frequency response. Turn clockwise for more brightness (boost), counter-clockwise for a warmer tone (cut).
- Bass: Adjusts the low-frequency response. Turn clockwise for more depth (boost), counter-clockwise for a tighter bass sound (cut).
The active preamp allows for significant tonal shaping, providing both boost and cut capabilities for treble and bass frequencies.

Playing Position
Whether standing or sitting, ensure a comfortable playing position that allows for easy access to all frets and controls. The contoured body design is crafted for ergonomic comfort.
Maintenance
Cleaning
Regularly wipe down your bass with a soft, lint-free cloth after each use to remove sweat and fingerprints. For a deeper clean, use a guitar-specific cleaning solution on the body and a fretboard conditioner on the fretboard (if applicable, for Jatoba or Rosewood; Maple fretboards can be cleaned with a damp cloth).
String Replacement
Strings should be replaced periodically, depending on usage. Old strings can lose their tone and intonation. When replacing strings, change them one at a time to maintain neck tension. Use nickel string material as specified for this model.
Truss Rod Adjustment
The truss rod, located at the base of the neck, allows for adjustment of neck relief. This should only be performed by experienced individuals or a qualified technician to avoid damage to the neck. Minor adjustments can correct excessive fret buzz or high action.

Troubleshooting
- No Sound: Check the instrument cable, amplifier connection, and ensure the 9V battery in the bass is fresh and correctly installed. Verify the volume knob on the bass and amplifier are turned up.
- Weak or Distorted Sound: Replace the 9V battery. Check for loose connections in the cable or output jack.
- Fret Buzz: This can be caused by low action, an uneven fretboard, or insufficient neck relief. Minor adjustments to the bridge saddles or truss rod may be necessary. Consult a technician if unsure.
- Poor Intonation: If notes are out of tune higher up the neck, the bridge saddles may need adjustment. This requires a tuner and a small screwdriver.
