You own an old guitar and want to know more about it? We offer expertises for CHF 100 per instrument in which we meticulously check every detail of your guitar. You will then receive a certificate which is personally signed by the owner of Gitarren Total, Patrick Geser, confirming the condition, originality and current market value. This certificate is of great value for private sale, for insurance or for putting it in a frame next to your guitar.
