Guitar Guitar Equipment & Gear 1 — Questions and Answers
Question 1: What is the primary function of a guitar's truss rod?
- To adjust the intonation at the bridge
- To control the relief (bow) of the guitar neck (Correct answer)
- To raise or lower the string action at the nut
- To connect the neck to the guitar body
Correct answer: To control the relief (bow) of the guitar neck
The truss rod runs through the neck and is adjusted to counteract string tension, controlling the amount of forward or back bow (relief) in the neck.
Question 2: What does string gauge refer to when purchasing guitar strings?
- The number of windings on each wound string
- The material composition of the string core
- The thickness/diameter of the strings measured in thousandths of an inch (Correct answer)
- The tension rating of the entire string set
Correct answer: The thickness/diameter of the strings measured in thousandths of an inch
String gauge refers to the diameter of the strings, typically measured in thousandths of an inch — for example, a light set might have a .010 first string.
Question 3: What is the nut on an acoustic or electric guitar?
- A small piece at the headstock end of the fretboard that spaces and guides the strings (Correct answer)
- The locking mechanism that secures the strings at the bridge
- The metal fastener that connects the neck plate to the body
- The adjustable saddle piece that sets intonation
Correct answer: A small piece at the headstock end of the fretboard that spaces and guides the strings
The nut is a small piece (often made of bone, plastic, or synthetic material) located at the top of the fretboard that spaces the strings evenly and sets their height before they reach the tuning pegs.
Question 4: What is the purpose of a capo?
- To lower the overall pitch of the guitar by adding string mass
- To mute unwanted string noise during fingerpicking
- To clamp across all strings at a given fret, raising the pitch of all open strings (Correct answer)
- To adjust string action across the entire fretboard
Correct answer: To clamp across all strings at a given fret, raising the pitch of all open strings
A capo clamps across all strings at a specific fret, shortening the vibrating string length and raising the pitch of all strings simultaneously — useful for playing open chord shapes in higher keys.
Question 5: What does guitar 'action' refer to?
- The responsiveness of the guitar's onboard electronics
- The height of the strings above the fretboard (Correct answer)
- The total weight and balance of the guitar body
- The number of playable frets accessible on the neck
Correct answer: The height of the strings above the fretboard
Action refers to the height of the strings above the frets — low action is easier to play but risks fret buzz, while high action requires more finger pressure but typically buzzes less.
Question 6: What material is traditionally preferred for guitar nuts due to its tonal properties and durability?
- Plastic
- Aluminum
- Bone (Correct answer)
- Ebony wood
Correct answer: Bone
Bone is the traditional and widely preferred nut material because it provides excellent tone transfer, sustain, and durability compared to cheaper plastic alternatives.
Question 7: What does a guitar's 'scale length' refer to?
- The total length of the guitar from the strap pin to the headstock
- The vibrating length of the string measured from the nut to the bridge saddle (Correct answer)
- The number of frets on the guitar neck
- The width of the neck at the first fret
Correct answer: The vibrating length of the string measured from the nut to the bridge saddle
Scale length is the vibrating string length measured from the nut to the bridge saddle — common examples are Fender's 25.5" and Gibson's 24.75", which affect string tension and fret spacing.
