Electric guitar and amplifier: the basics

In short: An electric guitar only produces its characteristic, audible sound through an amplifier, since the pickups alone only deliver a weak electrical signal. The interplay of both devices shapes the sound more strongly than with almost any other instrument.

In more detail: Magnetic pickups convert the vibration of the metal strings into an electrical signal, which is carried to the amplifier via a cable.

In detail

• Single-coil vs. humbucker: Single-coil pickups sound clear and bright, while humbuckers deliver a fuller tone and suppress hum.
• Tube amplifiers: Produce a warm tone, often perceived as especially musical, through vacuum tubes, particularly when overdriven.
• Solid-state amplifiers: Cheaper, lighter, and lower-maintenance than tube amps, but with a different tonal character.
• Effects pedals: Pedals connected between guitar and amp change the sound through distortion, reverb, delay, or other effects.
• Speaker cabinet: In separated systems, the cabinet and its speakers significantly determine the final tonal character.
• Distortion: Overdriving the signal produces the gritty sound typical of rock and metal.
• Cables and wireless: High-quality cables or digital wireless systems transmit the signal from guitar to amplifier with minimal loss (akkorde-grundlagen).
