As a musician and guitar enthusiast, I would often visit Yamaha's archives website for speficiations about certain Yamaha guitars I was interested in. However, recently while trying to do a search, I learned that Yamaha had taken down their much useful informational website where we could search model numbers for such specs. After looking around, I found this website which had a downloadable original spreadsheet of all of the model numbers and specs (linked below). I then compiled the databases and made this online tool where I can continue to search for the models and specs similar to Yamaha's old website.
Seagull Guitars are Now Available! Select from the menu above.
In the near future, I will create additional searching tools, such as listing by Wood Type, Headstock Type, Nud Width, Production Dates, Limited Productions, ETC... - I will also be adding a Serial Decoder, so you can verify Model Numbers.
Feel free to use this tool for your personal use. However, I assume no responsability for the information displayed. I am not responsible for misidentified model numbers or incorrect information. Use this at your own risk and / or discretion. I have tried my best to make sure all the data in this site is complete (Based on the downloadable spreadhseet found Here). This is also linked below..
