Question about Johnson Ma100 Lynchburg Mandolin

2 Answers

Sound post has fallen inside F style Johnson mandolin.

The sound post has become unattached inside the mandolin body. The body has also sunk in at one of the sound holes compared to the other side which causes the bridge to be out of alignment and I can't get the mandolin tuned.

You may be able to help this prob. your self. You will need a set of hemostats about 10 in. long. A nickel sized dental mirror a flexible LED light . First of all unstring it , put strings a side.Next look in side to the under side of the top of your Mandolin .With your lite and mirror you should see a spot where the post was org. placed.Now with your hemostats reinstall the post. Now this is like building a ship in a bottle, but it can be done , but just a little at at time. You need to lift up the whole top. Remember the top did not drope down all at once, nor will you rase it up all at one time. A little eack day untill you have reached a perpendicular point . One more thing, you post fell because the insturmant was to dry.You need to keep it humidfided . Take it to the shower with you. dont get it wet let it soak up the steam, it will help you get the post back up right and it will love you four it. Get a humidfier for it OK

You need to find a good luthier (Instrument craftsman) in your area. Trying to fix this one yourself could really damage your instrument. I would suggest detuning it until you can take it in.

FYI...the sound post doesn't really hold anything together, it just transfers vibrations through the back of the body. If the face of your Mando is sinking in, there are likely to be other things going on. ie humidity issues, structural issues, etc..

Hope this helps and you can save your Mando...

    If you can see the socket, get a crochet needle that fits inside the socket and pull it back up through the hole. Good luck!

    The socket that the guitar cable plugs into has become unscrewed and fallen into the body of the amp. Is there a simple way of retrieving it from inside easily?

    Yes, it should be as straight forward as gaining access inside the amp, locating the jack and putting it back, however make sure it is unplugged from the mains! If you are unsure if you are up to the task you should take it to your local technician as this will be an inexpensive fix

    The body has sunk on my mandolin between the sound holes. I took the old strings off and cleaned it and started to restring it and the bridge was pushing down. I didn't notice it until the strings started...

    Sounds like the bridge was either in the wrong place or the string tension excessive.

    Sometimes there are low, medium, and high tension grades of strings.
    Find out what your mandolin requires.

    If the strings are snapping, you are tuning them wrong. They should NOT break with 10% over the final tuning. It sounds like you may be using the wrong strings.

    De-string it to see if the wood will recover. If it doesn't take the instrument to a Luthier for repair.

    Guitar strings on a mandolin.

    Looking at your desired notes the mandolin is standard tuned to gdae.
    So three of the four notes are already available, just put the "d" mando strings where the "g" ones would go and the "g" ones where the "D" ones would go the highest is already a "e" and I am sure the "a" would tune up to a "B" with little risk.
    You can also
    look at string sets made for the madochello or possbly octave mandolin.

    Good luck,

    The dude.
