Setup

1. Unboxing and Initial Inspection

Carefully remove the guitar from its packaging. Inspect the instrument for any signs of damage that may have occurred during shipping. Ensure all included accessories, such as the tremolo arm and adjustment wrenches, are present.

2. Tuning

Tune the guitar using a reliable electronic tuner. The Lo-Pro Edge tremolo system requires specific tuning procedures. Ensure the locking nuts at the headstock are loosened before tuning the main tuners. Once tuned, tighten the locking nuts and use the fine tuners on the tremolo bridge for minor adjustments.

3. Tremolo System Adjustment (Lo-Pro Edge)

The Lo-Pro Edge tremolo is factory-set. However, environmental changes or string gauge changes may require adjustment. Refer to the official Ibanez tremolo manual for detailed instructions on spring tension, bridge height, and intonation adjustments. Incorrect adjustments can affect tuning stability and playability.

Operating

The RG8570 features a standard control layout:

• Volume Knob: Controls the overall output level of the guitar.
• Tone Knob: Adjusts the treble response, from bright to warm.

2. Pickup Selector Positions

1. Position 1 (Bridge): Bridge Humbucker (DiMarzio Tone Zone) for powerful, aggressive tones.
2. Position 2: Bridge Humbucker (split coil) + Middle Single-coil (DiMarzio True Velvet) for bright, articulate tones.
3. Position 3 (Middle): Middle Single-coil (DiMarzio True Velvet) for classic single-coil sounds.
4. Position 4: Neck Humbucker (split coil) + Middle Single-coil (DiMarzio True Velvet) for clear, bell-like tones.
5. Position 5 (Neck): Neck Humbucker (DiMarzio Air Norton) for warm, smooth lead tones.

Maintenance

1. Cleaning

Regularly wipe down the guitar body, neck, and hardware with a soft, lint-free cloth after each use. For the body, use a guitar-specific polish sparingly. For the ebony fretboard, use a fretboard conditioner periodically to prevent drying and cracking.

2. String Replacement

Replace strings regularly to maintain tone and playability. When replacing strings on a Lo-Pro Edge tremolo, it is recommended to replace them one at a time to maintain bridge balance. Use the same gauge strings to avoid significant tremolo adjustments.

3. Hardware Inspection

Periodically check all screws and nuts for tightness, especially on the tuners, bridge, and strap buttons. Do not overtighten. Lubricate moving parts of the tremolo system with a small amount of specialized lubricant if squeaking or stiffness occurs.

Troubleshooting

• No Sound: Check cable connections, amplifier power, guitar volume knob, and pickup selector position. Ensure the guitar cable is fully inserted into both the guitar and amplifier.
• Buzzing/Fretting Out: This can be caused by low action, uneven frets, or improper neck relief. Consult a qualified guitar technician for adjustments.
• Poor Tuning Stability: Ensure strings are properly stretched, locking nuts are tight (but not overtightened), and the tremolo system is balanced. Worn strings can also cause tuning issues.
• Scratchy Pots/Switch: Dust or dirt can accumulate in the volume/tone pots or pickup selector switch. Use a contact cleaner designed for electronics, applied sparingly.
