Terms of use

Last updated: November 9, 2026. By using this site you agree to these terms.

Results are estimates

The decoders apply published serial number formats. Results are estimates of a build date. They are not an appraisal, a valuation or an authentication, and a matching serial does not prove a guitar is genuine. For a definitive answer, contact the maker.

No warranty

The site is provided as is, without warranty of any kind. We are not responsible for decisions you make, such as buying or selling a guitar, based on a result. Use the tools and guides as a starting point and check with the maker or a qualified technician.

Trademarks and independence

This site is not affiliated with, endorsed by or sponsored by any guitar maker. Brand and model names belong to their owners and are used only to describe the guitars a rule applies to.

External links

We link to other websites, including makers' own pages. We do not control them and are not responsible for their content.
