- Connect the other end of the guitar cable to the input jack on your amplifier.

Playing Techniques
The Donner DJB-510 is suitable for various playing styles. Experiment with fingerstyle, picking, and slapping to find your preferred sound. The laurel fingerboard and modern "C" neck profile are designed for comfortable playability.
Maintenance
Regular maintenance will help preserve your instrument's playability and appearance.
- Cleaning: After each use, wipe down the strings, fretboard, and body with a soft, dry cloth to remove sweat and grime. For a deeper clean, use guitar-specific cleaning products.
- String Replacement: Strings should be replaced periodically, depending on usage. Old strings can lose their brightness and intonation. When replacing, change one string at a time to maintain neck tension.
- Storage: Store your bass 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 direct sunlight.
- Neck Adjustment: The neck of the bass guitar may require occasional adjustment (truss rod adjustment) due to changes in humidity or string tension. This is typically a task for an experienced technician.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or weak sound | Loose cable connection, amplifier off, volume knobs down, faulty cable. | Check all cable connections, ensure amplifier is on and volume is up, check bass volume/tone knobs, try a different cable. |
| Buzzing or rattling strings | Low string action, uneven frets, worn strings, improper playing technique. | Adjust string action (bridge height), replace strings, consult a technician for fret leveling, review playing technique. |
| Poor intonation (notes out of tune higher up the neck) | Incorrect bridge saddle position, old strings. | Replace strings, adjust bridge saddles (intonation adjustment), consult a technician. |
| Scratchy sound when adjusting knobs | Dust or dirt in potentiometers. | Apply contact cleaner to the potentiometers (consult a technician if unsure). |
