Setup
Unpacking and Initial Inspection
Carefully remove your guitar from its softshell case. Inspect the instrument for any signs of damage that may have occurred during shipping. Ensure all components are present and intact.
Tuning Your Guitar
Your Martin 000C Jr E StreetMaster should be tuned to standard EADGBe tuning. Use a reliable electronic tuner for accuracy. Gently turn the tuning pegs to adjust the string tension until each string reaches its correct pitch.

Stringing Your Guitar
When replacing strings, use light gauge phosphor bronze strings for optimal tone and playability. Thread each string through its corresponding bridge pin hole, ensuring the ball end is securely seated. Wind the string around the tuning post, making sure to leave enough slack for a few wraps. Tune to pitch.
Operating
Playing the Acoustic Guitar
The 000 Junior body size and Performing Artist neck profile are designed for comfortable playing, whether you prefer fingerstyle or flatpicking. Experiment with different strumming patterns and picking techniques to explore the guitar's dynamic range and balanced tone.

Using the Martin E1 Electronics
Your guitar is equipped with Martin E1 electronics for amplified performance. Locate the controls on the upper bout of the guitar. These typically include volume, tone, and a built-in tuner. Connect a 1/4" mono jack cable from the guitar's output jack (located at the bottom strap button) to an amplifier or sound system.
- Volume Control: Adjusts the overall output level of the amplified sound.
- Tone Control: Shapes the tonal characteristics, allowing you to dial in brighter or warmer sounds.
- Built-in Tuner: Activate the tuner to quickly and accurately tune your guitar. The display will guide you to the correct pitch.

Maintenance
Cleaning Your Guitar
Regularly wipe down your guitar with a soft, lint-free cloth after each use to remove sweat and oils. For a deeper clean, use a guitar-specific polish or cleaner on the body and a fretboard conditioner on the fretboard. Avoid harsh chemicals that can damage the finish.
Humidity Control
Acoustic guitars are sensitive to humidity changes. Maintain a relative humidity level between 45-55% to prevent warping, cracking, or other damage to the wood. Use a guitar humidifier in dry environments and a dehumidifier in overly humid conditions.
String Replacement
Replace strings regularly, typically every 1-3 months depending on playing frequency, to maintain optimal tone and playability. Old strings can sound dull and be harder to keep in tune.
Troubleshooting
- Buzzing Strings: Check string height (action) and neck relief. Minor adjustments can often resolve buzzing. If unsure, consult a qualified guitar technician.
- Poor Intonation: If notes played at the 12th fret are out of tune with open strings, the intonation may need adjustment. This typically requires professional setup.
- No Sound from Electronics: Ensure the 1/4" cable is fully inserted into both the guitar and amplifier. Check the battery in the Martin E1 system. Verify amplifier settings and volume levels.
- Tuning Instability: New strings may take time to stretch and settle. Ensure strings are properly wound on tuning posts. Extreme temperature or humidity changes can also affect tuning.
