Top 10 Questions for Fretted Instrument Inspector Interview

1. How would you inspect the intonation of a guitar?

To inspect guitar intonation, I would first check the tuner to ensure the guitar is in tune. Then, I would play each string at the 12th fret and compare the pitch to the open string.

• If the string is sharp at the 12th fret, the bridge saddle needs to be moved back towards the tailpiece.
• If the string is flat at the 12th fret, the bridge saddle needs to be moved forward towards the nut.

2. What are the key factors to consider when inspecting the neck of a guitar?

When inspecting a guitar neck, several factors must be considered:

Neck Relief

• Check if there is a gap between the strings and the fingerboard at the seventh fret.
• The gap should be around 0.010 inches
• Adjust the truss rod to achieve the correct neck relief.

Neck Bow and Twist

• Lay a straightedge along the side of the neck from the nut to the bridge.
• Check for any gaps between the straightedge and the neck.
• Adjust the truss rod to correct any bowing or twisting.

Fret Leveling

• Check that the frets are level using a fret rocker.
• Level the frets with a fret file if any are uneven.

3. How would you identify and repair a loose or rattling fret?

To identify a loose or rattling fret, I would tap on each fret with a rubber mallet. If a fret is loose, it will produce a dull sound or rattle.

To repair a loose fret, I would remove the string above the fret and use a fret puller to gently pull the fret out of the slot. I would then clean the slot and the bottom of the fret, apply some fret glue, and press the fret back into place. I would then recrown the fret and polish it.

4. What are the common causes of buzzing on a fretted instrument?

Common causes of fret buzz on a fretted instrument include:

• Loose or rattling frets
• Improper neck relief
• High action (distance from the strings to the fingerboard)
• Worn or uneven frets
• Loose or rattling truss rod

5. How would you inspect the electronics of an electric guitar?

To inspect an electric guitar’s electronics, I would first check the output jack to ensure it is securely connected. I would then use a multimeter to check the continuity of the pickups, selector switch, and volume and tone pots.

• I would also check the soldering joints on all the electronic components to ensure they are clean and secure.
• Finally, I would plug the guitar into a amplifier and test all the pickup positions and controls to ensure they are functioning properly.

6. What are the different types of finishes used on fretted instruments?

The different types of finishes used on fretted instruments include:

• Nitrocellulose lacquer
• Polyurethane
• Acrylic
• Oil-based finishes (such as tung oil or linseed oil)
• Wax finishes

Each type of finish has its advantages and disadvantages, so the choice of finish depends on the desired look, feel, and tone of the instrument.

7. How would you repair a cracked guitar body?

To repair a cracked guitar body, I would first clean the crack and surrounding area with a damp cloth. I would then apply a thin layer of wood glue to the crack and clamp it together. I would use a soft cloth between the clamp and the guitar to prevent damage to the finish.

• Once the glue has dried, I would sand the area smooth and apply a touch-up finish to match the rest of the guitar.

8. What are the common causes of a guitar going out of tune?

The common causes of a guitar going out of tune are:

• Changes in temperature or humidity can affect the tension of the strings, causing them to go out of tune.
• Loose tuning pegs or a slipping nut can allow the strings to slip, causing the guitar to go out of tune.
• Stretching or breaking in new strings can also cause the guitar to go out of tune.
• A damaged or worn-out bridge or nut can also cause the guitar to go out of tune.

9. How would you troubleshoot a problem with a guitar’s pickup?

To troubleshoot a problem with a guitar’s pickup, I would first check the output jack to ensure it is securely connected. I would also check the continuity of the pickup with a multimeter.

• If the pickup is not receiving power, I would check the wiring and solder joints to ensure they are secure.
• If the pickup is receiving power but not producing any sound, I would check the pickup’s magnets and coils for damage.

10. What are the different types of guitar strings?

The main types of acoustic and electric guitar strings are:

• Acoustic guitar strings: Steel strings, nylon strings, fluorocarbon strings
• Electric guitar strings: Nickel-plated steel strings, stainless steel strings, cobalt strings

Each type of string has a unique sound and feel, so the choice of string depends on the desired tone and playing style.
