1. 1

   What principle allows a conventional magnetic electric guitar pickup to produce an electrical signal?

   A A vibrating steel string changes the magnetic flux through a coil B String vibration changes the air pressure inside the pickup C Fret contact generates electricity through friction
2. 2

   Why does a bridge pickup generally sound brighter than a neck pickup on the same guitar?

   

   A The bridge pickup receives power directly from the bridge B The string moves less near the bridge and its harmonic balance emphasizes higher frequencies C The bridge pickup always uses a smaller tone capacitor
3. 3

   How does a traditional humbucker reduce mains-frequency hum while retaining the guitar signal?

   A Its capacitor blocks all frequencies below the played note B Its metal cover prevents every external field from reaching the coils C Its two coils are arranged so common hum cancels while the string signals add
4. 4

   On a typical two-pickup guitar with a three-way selector, what does the centered switch position select?

   

   A The bridge pickup with its tone control bypassed B The neck and bridge pickups together C The neck pickup with one coil disabled
5. 5

   What does a standard passive volume control primarily do when it is turned down?

   A It diverts more of the pickup signal toward ground, reducing output B It lowers the magnetic strength of the pickups C It increases the resistance of the guitar cable
6. 6

   What is the main function of the capacitor in a conventional passive tone-control circuit?

   A To increase pickup output through stored battery power B To block low frequencies from reaching the output jack C To route increasing amounts of high-frequency content to ground
7. 7

   Which type of pickup is highlighted at the bridge in the illustrated HSS pickup layout?

   

   A A humbucker B A single-coil C A piezo saddle pickup
8. 8

   Compared with a 250 kΩ volume potentiometer, what is a common tonal effect of using a 500 kΩ potentiometer with passive pickups?

   A It creates stronger hum by reversing pickup polarity B It loads the pickups less and generally preserves more high frequencies C It converts passive pickups into active pickups
9. 9

   What happens electrically when a conventional humbucker is coil-split?

   A Both coils are connected in parallel instead of series B The pickup is disconnected from the volume control C One coil is bypassed or grounded so the other coil remains active
10. 10

    What problem can occur if a magnetic pickup is adjusted excessively close to the strings?

    

    A Magnetic pull can cause tuning instability, warbling, or reduced sustain B The tone capacitor can permanently lose its capacitance C The strings can no longer induce any voltage in the coil
11. 11

    Why do most active electric guitar pickups require a battery?

    A The battery magnetizes ordinary nickel strings B The battery powers an onboard preamplifier or active circuit C The battery mechanically increases string vibration
12. 12

    In the illustrated mono output jack, what should the terminal connected to the contact touching the plug's tip normally carry?

    

    A The bridge safety ground only B Battery power sent directly to passive pickups C The guitar's hot output signal
13. 13

    Why can positions 2 and 4 on many three-single-coil guitars produce less hum than positions using one pickup alone?

    

    A Those positions automatically activate a hidden noise-gate circuit B A reverse-wound, reverse-polarity middle pickup can cancel hum with its partner C The selector disconnects the guitar's ground wire in those positions
14. 14

    Wax potting is commonly used to reduce squealing from a microphonic pickup because it does what?

    A Stabilizes coil windings and other parts that could vibrate acoustically B Raises the pickup's DC resistance by adding more wire C Reverses the magnetic polarity of one coil
15. 15

    Two pickups sound unusually thin and lose substantial bass only when selected together. What is the most likely cause?

    A Both pickups have identical DC resistance B The volume potentiometer has a value above 250 kΩ C The pickups are electrically out of phase with each other
16. 16

    Compared with parallel wiring, what is the usual result of connecting a humbucker's two coils in series?

    

    A Higher output with a fuller, more mid-focused response B Complete loss of hum cancellation in every wiring arrangement C Lower output with a brighter response in all cases
17. 17

    A guitar's signal cuts out when the cable is moved at the output jack. What should be inspected first?

    A The pickup magnets for excessive strength B The jack's solder joints, contact tension, and mounting tightness C The fretboard radius and neck relief
