List of Questions and Answers for a Job Interview for Musical Instrument Repairer

Question 1

How do you approach diagnosing a buzzing sound on an acoustic instrument?

Answer:

I start with a systematic inspection, checking the nut slots, fret heights, and bridge saddle. I use a straightedge to verify neck relief and inspect the internal bracing for loose glue joints, as these are common culprits for vibrations.

Question 2

What is your experience with fretwork, specifically leveling and crowning?

Answer:

I have [specify number] years of experience using specialized leveling beams and crowning files. I prioritize consistency across the entire fretboard and always finish with a thorough polish to ensure smooth string bends.

Question 3

How do you handle a situation where a customer is unhappy with a repair result?

Answer:

I listen to their concerns without being defensive and play the instrument in front of them to identify the specific issue they are experiencing. I then explain the technical limitations or offer a secondary adjustment to bring the instrument closer to their preference.

Question 4

What tools are essential for a professional repair bench?

Answer:

A well-equipped bench needs precision measuring tools like radius gauges and feeler gauges, a variety of clamping systems, high-quality files and chisels, and specialized adhesives like hide glue or high-grade epoxy.

Question 5

How do you manage your time when you have multiple instruments waiting for repair?

Answer:

I use a ticketing system to prioritize repairs by urgency and complexity. I group similar tasks—like all restringing or all finish work—together to maximize efficiency and minimize tool setup changes.

Question 6

Describe your process for fixing a crack in a solid wood instrument.

Answer:

I first assess the humidity levels and structural stability of the area. I carefully clean the crack, apply the appropriate adhesive, and use specialized cleats or clamps to ensure the wood remains flush during the curing process.

Question 7

How do you stay updated on new repair techniques and tools?

Answer:

I regularly attend [mention workshops or trade shows] and follow industry forums and technical literature. I also enjoy experimenting with new methods on test instruments to refine my skills.

Question 8

What is the most challenging repair you have ever completed?

Answer:

I once restored a [mention instrument type] that had suffered significant water damage. It required complete disassembly, re-gluing of several braces, and a full refinish, but seeing the instrument return to a playable state was incredibly rewarding.

Question 9

How do you ensure intonation is perfect after a bridge adjustment?

Answer:

I use a high-precision strobe tuner to check the pitch at the twelfth fret against the open string. I make micro-adjustments to the saddle position until the intonation is accurate across the entire scale length.

Question 10

Do you have experience with vintage instrument restoration?

Answer:

Yes, I have worked on [mention specific vintage instruments]. I understand the importance of preserving the instrument’s original components and value while ensuring it remains functional for the player.

Question 11

How do you handle delicate finishes during a repair?

Answer:

I use protective padding and masking tape specifically designed for instruments to ensure no damage occurs to the surrounding finish while I am working on hardware or wood repairs.

Question 12

What safety precautions do you take when working with chemicals or dust?

Answer:

I always wear appropriate PPE, including masks for dust and respirators for finishes. My workstation is equipped with [mention ventilation or vacuum system] to maintain a healthy environment.

Question 13

How do you explain technical repair jargon to a beginner musician?

Answer:

I use analogies that relate to the player’s experience, such as comparing “action” to the height of the strings off the fretboard. My goal is to make them feel confident in the process rather than overwhelmed.

Question 14

What is your approach to working on a brand-new instrument versus a family heirloom?

Answer:

Both require the same technical precision, but the heirloom requires an extra layer of care regarding the history and provenance of the piece. I treat every instrument with the same respect, regardless of its market value.

Question 15

How do you handle a repair that you realize is beyond your current skill level?

I check the neck angle and the height of the bridge saddle. If the saddle is already at its lowest point and the action is still too high, a neck reset is likely the correct structural solution.

Question 18

What role does humidity play in your repair work?

Answer:

Wood is a living material that reacts to moisture. I maintain a controlled environment in the workshop and always advise clients on the proper humidity levels for their instruments to prevent future issues.
