1. What Exactly Is a Guitar Pickup?
A guitar pickup is a transducer, converting the mechanical energy of vibrating guitar strings into an electrical signal. This signal is then amplified to produce the sound you hear. Think of it as the microphone for your electric guitar, capturing the nuances of your playing and transmitting them to your amplifier, a fundamental aspect for any guitar player.
1.1. Breaking Down the Components of a Pickup
A typical guitar pickup comprises magnets and copper wire. The magnets create a magnetic field, and the copper wire, wound around the magnets, acts as an inductor. When a steel guitar string vibrates within this magnetic field, it disrupts the field, generating an electrical current in the wire. The specifics of the magnets and wire influence the pickup’s tonal characteristics.
1.2. The Role of Pole Pieces
Pole pieces are the magnetic cores (often adjustable screws or rods) that focus the magnetic field. Their proximity to the strings significantly affects the pickup’s sensitivity and tonal balance. Adjustable pole pieces allow for fine-tuning the output of individual strings, helping you achieve a balanced sound across the fretboard.
1.3. Seth Lover’s Insight on Pickups
Seth Lover, a pioneer in pickup design, offers a unique perspective. He explains that the magnetic field from the pickup magnetizes the strings. The vibration of these magnetized strings within the pickup’s magnetic field induces a voltage in the coil, which is then amplified, shaping the final sound. Lover emphasizes the interaction between the magnetic field and the strings in producing the electrical signal.
"...the magnetic field comes up to the strings there and magnetises the strings. That’s one of the things that most people don’t understand. They figure that string is waving there and cutting the magnetic lines of force. Nuts. That isn’t it. The magnet, all it does is magnetise the string. Now you’ve got a waving magnetic field. And we have a fixed coil with a waving magnetic field to induce voltage. If you want to, take the magnet out. Once you’ve magnetised your strings, it will play until the string loses it. Players think the string, the magnetic field from the magnet, comes up to the string and by twisting the magnetic flux back and forth that’s what induces the voltage. That’s not what happens." *(Seth Lover, from a 1978 interview with Seymour Duncan)*1.4. Different Magnet Types and Their Influence on Tone
Different magnet types alter the pickup’s sound. Alnico magnets, made from aluminum, nickel, and cobalt, are categorized into grades like Alnico II, IV, and V. Alnico II magnets provide a warmer, softer tone, while Alnico V magnets offer a brighter, punchier sound. Ceramic magnets, often used in high-output pickups, deliver a more aggressive, modern tone.
1.5. Single Coil vs. Humbucker Designs: A Quick Comparison
Single-coil pickups, known for their bright and clear sound, are more susceptible to noise and hum. Humbuckers, featuring two coils wired in series, cancel out much of this noise while delivering a thicker, warmer tone. The choice between single coils and humbuckers often depends on the desired musical style and playing environment.
