Serial Number Guide
1997–1999 & 2010–Present
Serial numbers follow this format: YY####MM
- YY = Year of manufacture (last two digits)
- #### = Sequential build number for that body style
- MM = Month of manufacture
Example: 18485703
Built in March 2018
4,857th instrument of that body style
2000–2009
Serial numbers during this period follow a slightly different format: Y####MM
- Y = Last digit of the year
- #### = Sequential build number
- MM = Month of manufacture
Example: 7198708
Built in August 2007
1,987th instrument built
Note: Larger body styles will have lower sequential numbers due to fewer instruments being produced in those categories.
Q. How do I change my strings?
We recommend that you change one course of strings at a time. This will keep the floating bridge in place and properly intonated.
To simplify string installation, begin by gently bending the string’s loop end upward. This slight angle allows the string to glide more easily along the tailpiece ramp.
For added protection, we recommend inserting the string from the bridge side of the tailpiece. This helps avoid accidental scratches to the top of your instrument. Placing a soft cloth over the mandolin top will offer additional protection during the process.
Once the string is in place, give it a slight twist and guide the loop over the hook in a smooth motion. Make sure the loop is seated snugly near the base of the hook.
When you change your strings check the bottom of your bridge for a “T” marking and an arrow—this indicates the treble side. Make sure the saddle is installed in the correct orientation, with the arrow pointing toward the treble side of the mandolin. The bridge should lean slightly backward to provide optimal downward pressure on the top. Ensure the base of the bridge is making full, even contact with the instrument's top. If it’s not seated properly, you may need to loosen the strings slightly and gently pull the bridge back until it is seated.
Q. What strings do we use?
- Mandolin - D'Addario EJ 74
- Mandola - D'Addario EJ 72
- Octave - D'Addario EJ 80
- Mandocello - D'Addario EJ 78
Q. Why is my instrument buzzing?
- While played open: action is too low, or nut/saddle slots incorrect (If you've recently changed your strings, make sure your saddle is not backwards).
- While fretted a single fret: the next fret is too high
- Buzzes on frets 1-5: truss rod needs to be loosened and adjust action.
- Buzzes on frets 5-9: truss rod needs to be tightened and adjust action.
Q. String goes sharp?
- String is sticking in nut slot: first try graphite (pencil lead) in slots- slot may have to be widened.
Q. String goes flat?
- String is sticking in bridge slot: first try graphite (pencil lead) in slot- slot may have to be widened
- Machine heads may be worn and slipping.
Q. Intonation?
- Bridge should be perpendicular to the strings
- Check the average intonation of your instrument.
- If you've recently changed your strings make sure your saddle is not on backwards or that the bridge is not rocked or leaning forward
- If, while fretted at the 12th fret: Plays flat: move the bridge towards the peghead. Plays sharp: move the bridge towards the tailpiece.
