Guitar Cables: Choosing by Type, Length and Build

Every guitar cable carries the same small signal. What separates a good one from a humming nuisance is inside the jacket.

Length and Tone

Capacitance builds up

Every metre adds capacitance, which rolls off high frequencies. Long runs sound duller.

Practical ceiling

Keep instrument runs under six metres where possible. Beyond that, use a buffer.

Speaker runs

Speaker cable length matters less for tone but more for power loss.

Mixing them up

An instrument cable in the speaker path overheats; a speaker cable on a guitar invites hum.

What Stops the Hum

  1. Good shielding on the instrument cable.
  2. Keep the run away from power supplies and dimmers.
  3. Shorter runs where possible.
  4. Quality solder joints at both plugs.
  5. Isolate ground loops if hum persists at the amp.

FAQ

Are all guitar cables the same?

No. Shielding, capacitance and build quality differ widely.

Does cable length change tone?

Yes. Long unbuffered runs roll off highs.

Can I use a speaker cable for guitar?

No. It is unshielded and will hum.

How long should a guitar cable be?

As short as the stage allows, ideally under six metres.
