1. Introduction

The Gold Tone OM-800+ is an octave mandolin designed to be tuned one octave lower than a standard mandolin. This instrument features a compound radius fingerboard and an extended scale length, contributing to its playability. It is constructed with curly maple back and sides, an arched solid spruce top, and a mahogany body, which collectively enhance its tonal qualities, sustain, and volume. The OM-800+ is supplied with a hard shell case for protection and transport.

2.2 Tuning

The OM-800+ Octave Mandolin is typically tuned G-D-A-E, one octave lower than a standard mandolin. Use a reliable electronic tuner for accuracy. Tune each pair of strings to the corresponding note.

2.3 Bridge Adjustment

The bridge height can be adjusted to optimize string action and eliminate fret buzzing. If you experience buzzing, locate the small adjustment knobs on the bridge. Turning these knobs clockwise will raise the bridge, increasing the string height from the fretboard. Make small adjustments and re-check the playability until the desired action is achieved without buzzing.

3. Operating

3.1 Playing Technique

The OM-800+ features wider frets compared to a standard mandolin, which may require an adjustment in fingering technique. Experiment with different finger positions to find what is comfortable and effective for chords and melodies. The extended scale length contributes to its unique tonal characteristics.

3.2 Sound Characteristics

This octave mandolin produces a rich, lush, and deep tone, often compared to the lower range of a guitar but with the distinct mandolin string tuning system. It offers significant sustain, allowing notes to ring out longer than on a standard mandolin. Harmonics on this instrument are notably clear and resonant.

3.3 Using the Passive Pickup

The Gold Tone OM-800+ includes a built-in passive pickup. To use it, connect a standard instrument cable from the endpin jack to an amplifier or PA system. As it is a passive pickup, you may need to adjust the gain and equalization settings on your amplifier to achieve the desired sound. For optimal performance in live settings, further signal processing or a preamplifier might be beneficial.

4. Maintenance

4.1 General Care

To maintain the longevity and sound quality of your instrument:

• Always store the mandolin in its hard shell case when not in use to protect it from dust, humidity fluctuations, and physical damage.
• Avoid exposing the instrument to extreme temperatures or sudden changes in humidity. Wood instruments are sensitive to environmental conditions.
• Wipe down the strings and body with a soft, dry cloth after each use to remove oils and sweat.

4.2 String Replacement

Strings should be replaced periodically, depending on usage, to maintain optimal tone and playability. The OM-800+ uses custom gauge Phosphor Bronze strings. Replace one string at a time to maintain tension on the neck and bridge. Ensure new strings are properly seated in the bridge and nut slots.

4.3 Cleaning

For cleaning the body, use a soft, lint-free cloth. For stubborn grime, a small amount of instrument polish specifically designed for lacquered finishes can be used, applied sparingly to the cloth, not directly to the instrument. Clean the fretboard with a dry cloth; for deeper cleaning, consult a luthier or use specialized fretboard conditioners.

5. Troubleshooting

5.1 Fret Buzz

If you experience fret buzz, first check your playing technique to ensure proper finger placement and pressure. If the buzz persists, adjust the bridge height as described in Section 2.3. If the issue continues, the neck relief may need adjustment, which is best performed by a qualified instrument technician.

5.2 Pickup/End Pin Issues

Should the internal nut for the pickup or the end pin become loose or disconnected, it can lead to intermittent signal or the end pin falling out. This typically requires access to the instrument's interior. It is recommended to seek assistance from a professional instrument repair technician for these types of issues to prevent further damage.

5.3 Tuning Instability

If the instrument struggles to stay in tune, ensure the strings are properly stretched and seated. Check that the tuning machine screws are snug, but not overtightened. Extreme temperature or humidity changes can also affect tuning stability; allow the instrument to acclimate to its environment.
