Parts of an Electric Guitar Explained

An electric is the same map as an acoustic, plus a few new toys: pickups, knobs, and a switch. Here's what they all do.

Know the acoustic? Then you're most of the way here. An electric just trades the hollow body for a solid slab and adds toys. I love the toys. Let me give you the tour of the good stuff.

The Electric Extras

What's new versus an acoustic:

  1. 1Pickups — the bar-shaped magnets under the strings that 'hear' them and send the signal out.
  2. 2Pickup selector switch — flips between pickups (neck = warm/round, bridge = bright/cutting).
  3. 3Volume & tone knobs — control loudness, and how bright or mellow it sounds.
  4. 4Output jack — where the cable plugs in to reach the amp.
  5. 5Whammy / tremolo bar (on some guitars). The arm that dips the pitch for dive effects.

KEY IDEA

No amp, (almost) no sound

An electric on its own is very quiet. The sound lives in the amp. You'll need a cable and an amp (or a cheap headphone amp / phone app) to really hear it.

PRO TIP

Neck vs bridge pickup

Rule of thumb: the neck pickup is warmer and rounder (smooth stuff), the bridge pickup is brighter and punchier (cutting through). Flip the switch and listen.

Everything else, headstock, tuners, nut, frets, bridge, works just like an acoustic. Same fretting hand, same chords, same tuning. The extras are all about shaping the sound.

Don't sweat every knob on day one. Volume up, pick a pickup, play. Your ears will teach you what each control does faster than I can, and they won't be smug about it. Much.

Question 1 of 3

What do the pickups do?

The cheat sheet

  • Electrics add pickups, a selector switch, volume/tone knobs, and an output jack.
  • The sound lives in the amp. You need a cable and amp (or app) to hear it properly.
  • Neck pickup = warmer; bridge pickup = brighter.
  • Everything else works exactly like an acoustic.

Common questions

Can I learn on an electric without an amp?

You can practice fretting and chords unplugged, but it's very quiet and not much fun. A cheap headphone amp or an amp-sim app on your phone solves it for very little money.

What does the tone knob actually do?

It rolls off the high frequencies: turned up it's bright and cutting, turned down it's warmer and darker. Volume controls loudness; tone controls brightness.

What's the whammy bar for?

That metal arm (a tremolo/vibrato bar) lets you dip or wobble the pitch of the strings for dive-bombs and vibrato effects. It's optional — plenty of guitars don't have one.
