Regarde a l'arrière, moi j'avais le mm problème et ce n'était qu'un faux contact!
Dear Mr. Braun,
Thank you for your interest in Gibson products.
To better identify your guitar, it would be of great help if you could send us some picture of it in JPEG format (with a maximum size of 500KB per picture).
In details: one full front, full back, one of the front of the peghead and one of the back where the serial number is (make it as the serial number is clearly visible).
If you have any further queries, please do not hesitate to contact us again or refer to our webpage at

Kind regards,
