Topic: Can A Bad Chord Really Do This? |

I've been experiencing some noise that has been primarily associated with channel 2 of my rack rig. VP>RV-5>Mesa Boogie Studio Preamp>Mosvalve 500>2X15 JBL E-130's cabs. I finally started getting the same noise from channel one. I replaced one patch chord that seems to have cleaned it up. I AB'd everything else, and this seemed to be the only culprit.
Along with the noise has been a power drop. Can a bad connection(s) from a chord result in this type of problem? Or, do you think it will come back? It seems to have corrected the problem. What I don't get is how it would effect one channel initially and then carryover to the second channel. It is a mono signal, ot stereo.
Thanks for any relevant input. |

Sorry Tim, I don't want to make fun of a simple typo, but what a difference an "h" makes.
I had visions of some obscure combination of notes, of diminished and double sharp intervals, with the odd quarter tone thrown in, that could cause total amplifier meltdown.
It could have made me a fortune in the Death Metal Genre!
Anyway, your answer is quite definitely yes. A bad connection on a wire or lead or cable (or cord, as the US terminology goes) or plug can cause noise and loss of signal, in lots of ways.
We find these faults in the college studios very frequently, and our technician has a box marked "Lead Hospital" for the casualties on the waiting list for repair.
It will happen again, if and when the next connector goes faulty.
Cheers

Well Dave, you're right on the "h". Now that I've had a few cups of java, I realize your "disappointment" in the actual post (ha, ha). But, thanks for your reply. This has been a real pain in the neck for several weeks. It's bad to assume something is functional, that's so simple, to make you pull your hair out for a few weeks.
I have a box of "cords" as well that need repair. I guess it's time to get the soldering iron out, or go to all George L cables! Using an AB switch further complicates the number of cords that can go bad, but lighter than a second amp!
BTW, where are you located?
Thanks. |

The Malvern Hills are in the English West Midlands, famous for pure spring water (available free from the many wells around the Hills- or very expensive in posh hotels) and for healers, poets and musicians for the last thousand years or so. These include CS Lewis, Tolkien, Edward Elgar and me.
You can see a little glimpse of the place on my website:

The background to my Banner image with all the guitar headstocks is the view from the North Hill to the Worcestershire Beacon, and if you look in the Photo section, you can see the view from the top, looking down at the Priory Church and the Town.

Yes, I certainly do. The white headstock in the bottom left hand corner of the banner pic on my website is my National Console 8. If you listen to the track "I Love the South" you'll hear it on the intro. Click "Lyrics" then the title, then the little Radio.
Cheers
