Topic: Slight "buzz" or vibration on my Carvin 8 string l |

I have a Carvin 8 string lap with legs. C6 tuning. I found a picture on the forum that looks just like it so I included the link (this is not my guitar but looks identical)
http://bb.steelguitarforum.com/viewtopic.php?t=156790
It doesn't have near the tone of my Fender 8 string (I'm spoiled) but it is really thin and lightweight to to take out to little jams with minimum work. Handy. I use a standard set of Jagwire C6 strings Herb Remington).
The problem I have is some sort of "invisible buzz" or vibration in the guitar body when the bar is over certain strings at certain frets. Almost sounds like overtones from not muting properly, but more annoying as the body is physically vibrating. Its as if at certain places on the guitar all the strings are not even with each other and the odd string will buzz from not getting as solid a connection to the bar as the rest of the strings.I have tried all different sizes and weight bars with varying pressure and nothing helps. Is there anything I should look for in the nut or bridge to fix the problem?

If you can get it to make the noise with the bar while using a finger of your other hand (or get someone else to) to press on different places all over the instrument, (like each separate tuner button, different places on the bridge and nut, etc.) you might get lucky and track it down. Could be a string notch that is a bit loose.
Could be a loose wrapped string. Could be a component in the electrical compartment vibrating against something. My first double 8 was a Carvin, and I soon realized one of the telescoping legs had an interior rattle.
Could be possessed. I soak my finger picks in stump water when the Moon is full. |

Thanks. So far I think one of the legs is contributing to the noise and also when i push down real hard on the ends of the plastic pickup I lose a little buzz.
I think these two things will get rid of over half the buzz. I definitely need another person with me to check for buzzes in other areas of the guitar while I play.
The male end of the noisy leg I am referring to screws into the socket (female) on the body real tight, but after it is screwed in, there is a wobble to it. So the socket must be loose. I have to somehow figure out how to take that socket out of the wood body and then put it back in "real solid".
Any suggestions?

On one of mine, the threaded part of the leg was a metal steel plug in the end of the tube. I discovered that the end of the threaded part of one of the legs was protruding just a tiny bit deeper than the socket. I had to remove just a little bit of wood so that the bolt end could screw all the way in. Not being screwed in all the way had allowed it to wobble.
If I hadn't left the flange screws accessible, an alternative fix would have been to file off a bit of the end of the threaded part. I think it's also possible for the male plug to become loose in the leg end over time.
Have you tried swapping the legs around in different sockets to make sure it's the socket , and not a problem with one of the legs?
Yours may just have the end of the tube itself threaded, in which case it sounds like it is the female part. I take it the screws on the female part are not visible or accessible? I'm not sure how your female flanges are mounted. Photos would help. |

If you're getting a bit of rattle from your Legs.....you might want to put a generous wrapping of "plumber's tape" around the male threads. That might do the trick.
The "plumber's tape" is used when connecting gas lines and it prevents gas from escaping around the connections (where male meets female).
You should be able to get the tape at Home Depot...inexpensive. |

After some leg swapping it turns out the sockets were good. But if you gripped the male end from the end of the bad leg (looks like a screw) very tightly, asnd tryed to wiggle it... it would move.. so the screw end of the leg has to be "solidified".
That would take care of some of the problem.
There is still vibration when legs are removed and it is sitting on my lap.
I plan to put some time aside in the future to investigate this problem as it will take some time to figure it out.
