The Sanden Guitars come with a lifetime warranty to the first owner for as long as I are working as luthiers. That means that I will, without additional cost, repair or adjust any defects or flaws due to material imperfections. Any damage due to carelessness or negligence from the user will make the warranty void. Along with the warranty you will also receive a maintenance guide. My instruments are made of wood, which means they may react to large humidity variations. If you are unsure of anything regarding your guitar, don’t hesitate to contact me. You can read more under care. Any alteration on the instrument done by yourself or any person chosen by you without consulting me first may void the warranty. Read the maintenance guide carefully and follow its advice and you will have many happy moments with your Sanden Guitar.
