Location: Colorado Rocky Mountains | I have a question regarding cables clearly indicating that the signal should flow in a specific direction, i.e., with arrows pointing to which ends should go to the instrument and amp. Are these cables really unidirectional? Does it really matter? I'm no electrical engineer, but my rudimentary understanding of electronics suggests there really shouldn't be any difference. I notice this language on Monster cables and a few others. Am I missing something here? |

buy cables with good ends and good wire.
C B I is one of the best
good wire good connections no problems |

Location: NW Washington State | The cable can't be "unidirectional" and pass the AC signal from your guitar. It's possible that they have done something like lifting the shield at one end with the idea of limiting ground loops or noise. Does it sound any different when you plug it in "backwards"?
Monster Cables claims for their audio cables are full of complete BS and voodoo nonsense. Wouldn't surprise me if their instrument cables carry the same marketing spoo. Of course guitarists are much less gullible than those audiophools, so we wouldn't fall for that stuff.

Location: So. Cal. | There are many discussion on this subject in the world of audiophiles. "Burn-in" effect (most people seems to think this is BS) - new cable works either way, then it settles in one-way and works somewhat better than reversing direction. Connections (similar to what numbfingers pointed out) being different on the ends. Cable sheath and material bearing some (again, disputed) preferences.
In conclusion, a lot of the cables do have directional markings but few people agree on why. Some people always follow the arrows and others ignore them. |

Location: Ontario Canada | Working for the Bell Phone System for 34 years I was exposed to all manner of courses regarding sound and the transmission of same. I would agree with most others here, to limit a positive or negative the diode installation would merely have to be reversed one way or the other. I have never seen any such sheenanigans with guitar cables I have come across. We all know that the AC signal is not governed by the DC signal characteristics. Remember the decibel was named after Alexander Graham Bell.(1847--1922)
My grandkids are deaf because of their high levels of music at the rock concerts they attend.

Location: Utah | I believe that some of the cables have dual shielding with the guitar end lifted from ground. It in effect provides a signal ground common to both ends, but not an earth ground. The idea is to prevent a ground loop in the shielding. If you use the cable the wrong way, your shield is grounded to the guitar not the amp, potentially allowing hum into the shield. |

You have it nailed very accurately, we used to experience the guitar being "live" on a foggy damp night at an outdoor venue. Whenever the cable was reversed...end of hum and tingling shocks.
