1. Introduction
Welcome to the instruction manual for your new Johnson JG-100-SBL Student Acoustic Guitar. This guide provides essential information to help you set up, operate, maintain, and troubleshoot your instrument. The Johnson JG-100-SBL is designed for students, featuring a Catalpa top, back, sides, and neck, with a Maple fretboard and a 25.5-inch scale length. Please read this manual thoroughly to ensure proper use and care of your guitar.
2. Setup
2.1 Unpacking
Carefully remove the guitar from its packaging. Retain all packaging materials for future storage or transport. Ensure no accessories are left behind in the box.
2.2 Initial Inspection
Before proceeding, inspect the guitar for any signs of damage that may have occurred during shipping. Check the body, neck, headstock, and bridge for cracks, dents, or loose parts. If any damage is found, contact your retailer immediately.
2.3 Tuning the Guitar
Your guitar will require tuning before its first use. Acoustic guitars are typically tuned to standard E-A-D-G-B-e (from thickest to thinnest string). Use an electronic tuner for accuracy. Pluck each string individually and adjust the corresponding tuning peg until the tuner indicates the correct pitch.

3. Operating
3.1 Holding the Guitar
Sit comfortably in a chair without arms. Rest the guitar on your right thigh (for right-handed players) with the waist of the guitar body resting on your leg. The neck should be angled slightly upwards. Your right arm should rest over the top of the guitar body, allowing your hand to comfortably reach the strings over the soundhole. Your left hand will support the neck and fret the strings.
3.2 Basic Strumming
To produce sound, use a pick or your thumb to strum the strings. For basic strumming, move your hand in a downward motion across all six strings, then an upward motion. Practice maintaining a consistent rhythm. Experiment with different strumming patterns and dynamics.
3.3 Playing Chords
Chords are formed by pressing down on specific strings at specific frets with your left-hand fingers. Ensure each finger presses firmly just behind the fret wire to produce a clear, ringing tone. Start with simple open chords like G, C, D, and E minor. Practice transitioning smoothly between chords.
4. Maintenance
4.1 Cleaning
After each use, wipe down the strings and body of the guitar with a soft, dry, lint-free cloth. This removes oils and sweat that can corrode strings and damage the finish. For a deeper clean, use guitar-specific cleaning products sparingly.
4.2 String Replacement
Guitar strings should be replaced regularly, typically every 1-3 months depending on usage, or when they sound dull, corroded, or break. Replace strings one at a time to maintain neck tension. Use light gauge acoustic guitar strings for optimal playability and tone on this student model.
4.3 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 tension on the neck.
5. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Buzzing strings | Improper fretting, low action, warped neck, worn frets | Ensure firm fretting just behind the fret. Check neck relief and saddle height. Consult a guitar technician if issues persist. |
| Guitar won't stay in tune | New strings stretching, worn tuning pegs, improper string winding | Stretch new strings thoroughly. Ensure strings are wound correctly around tuning posts. Inspect tuning pegs for wear. |
| Dull or muted sound | Old strings, improper strumming technique, dampening by hand/arm | Replace old strings. Adjust strumming technique. Ensure no part of your hand or arm is muting the strings. |
