Introduction
This manual provides essential information for the proper setup, operation, and maintenance of your Yamaha APX600 Thin Body Acoustic-Electric Guitar. Please read this manual thoroughly to ensure optimal performance and longevity of your instrument.
The Yamaha APX600 is designed with a thin-line cutaway body, a unique under-saddle piezo pickup system, and a built-in tuner, making it suitable for both acoustic playing and amplified performances.
Setup
1. Unpacking and Initial Inspection
Carefully remove the guitar from its packaging. Inspect the instrument for any signs of damage that may have occurred during shipping. Retain the original packaging for future transport or storage.
2. Battery Installation
The APX600's active pickup system and built-in tuner require batteries for operation. Locate the battery compartment, typically on the side of the guitar's body near the preamp controls. This model requires two AA batteries.
- Open the battery compartment cover.
- Insert two fresh AA batteries, observing the correct polarity (+/-).
- Close the compartment cover securely.
Note: Always remove batteries if the guitar will not be used for an extended period to prevent leakage.
3. Initial Tuning
Before playing, tune your guitar. The APX600 features a built-in chromatic tuner for convenience.
- Press the "TUNER" button on the preamp to activate the tuner.
- Pluck each string individually. The display will show the note and indicate if it is sharp or flat.
- Adjust the tuning pegs until the display indicates the string is in tune (standard tuning: E-A-D-G-B-e).
- Press the "TUNER" button again to deactivate the tuner.

4. String Installation/Replacement
When replacing strings, use light gauge acoustic guitar strings (e.g., .012-.053). Replace strings one at a time to maintain neck tension. Consult a qualified technician if you are unsure about string replacement procedures.
5. Action Adjustment
The string height (action) is factory-set for optimal playability. If you experience fret buzz or find the action too high or low, adjustments to the truss rod or saddle may be necessary. These adjustments should ideally be performed by an experienced guitar technician to prevent damage to the instrument.
Operating the Guitar
1. Playing Acoustically
The APX600 is designed with a thin body for comfortable playability. Its new non-scalloped bracing pattern contributes to a responsive, dynamic acoustic tone. Hold the guitar comfortably, ensuring good posture for extended playing sessions.
2. Connecting to an Amplifier
To amplify your guitar's sound, connect a standard 1/4-inch instrument cable from the guitar's output jack (located at the bottom of the guitar) to an acoustic guitar amplifier or PA system input.

3. Using the Preamp Controls
The onboard preamp allows you to shape your amplified sound. The controls typically include:
- Volume: Adjusts the overall output level.
- 3-Band Equalizer (Low, Mid, High): Allows you to boost or cut specific frequency ranges to tailor your tone.
- Mid Freq: On some models, this control allows you to select the specific mid-range frequency to be affected by the Mid EQ knob.
- Tuner: Activates the built-in chromatic tuner (as described in the Setup section).
Experiment with these controls to find the sound that best suits your playing style and environment.
Maintenance
1. Cleaning
Regularly wipe down your guitar with a soft, dry, lint-free cloth after each use to remove sweat and fingerprints. For a deeper clean, use a guitar-specific polish or cleaner sparingly. Avoid abrasive cleaners or solvents.
2. String Care
Strings should be replaced regularly, depending on how often you play and your body chemistry. Worn or corroded strings can negatively affect tone and playability. Always wash your hands before playing to extend string life.
3. Fretboard Care
The rosewood fretboard benefits from occasional conditioning to prevent drying and cracking. Use a specialized fretboard oil or conditioner once or twice a year, applying it sparingly and wiping off any excess.
4. Storage
Store your guitar in a stable environment, away from extreme temperature changes, direct sunlight, and high humidity. A guitar case or gig bag provides protection from dust and minor impacts. If storing for extended periods, slightly detune the strings to relieve neck tension.
5. Battery Replacement
Replace the AA batteries in the preamp when the tuner display dims or the amplified sound becomes weak or distorted. Always use fresh, high-quality batteries.
