1965 Yamaha No. 150 Nylon Classical Guitar ***Upper Line East Indian Rosewood Model!!!******Japan Made Nippon Gakki Label!! The First True Yamaha Classical!!!******Unique Headstock Created Just For This Model!!!***Hopefully I will answer all your questions whether you’re a beginner or a pro. I am going to elaborate a lot about the design of this guitar. If you’re a beginner or unsure about some information print this auction and take it to someone you trust for verification or be sure to email any questions you have.Now about the instrument….is a very unusual Yamaha guitar. It is from the first generation of Yamaha classical guitars available in the USA. This model immediately followed the Dynamic Guitar line and despite what you may research on the internet, it is a true classical model not a folk guitar.If your familiar with the Yamaha Dynamic guitar line of the late 50’s your aware that those models were generally folk guitars with a hybrid brace pattern and a rounded club like neck. They have a unique and pleasant sound but are somewhat hard for players to get used to due to the neck shape.The No. 150 is a true classical guitar. Some owners have posted information that the neck or body is not of a classical design but I think they are misinformed. The body shape is

not like current Yamaha classicals which are all based on Spanish designs. This guitar is more like a German Hauser classical guitar in body shape. In either case a classical guitar is truly defined by its brace pattern and this one conforms to the traditional 7 fan brace Torres pattern. I’ve read in various posts that the model 150 was braced like a Ramirez with a transverse brace but this is once again misinformation.is a photo of the interior top of the guitar taken in a mirror.The 7 fan pattern is the most produced and popular pattern used for nylon guitars period; and produces the warm balanced sound that most people have come to associate with the classical guitar, if for no other reason than familiarity. Considering the age of the guitar I can’t criticize the designs structural integrity, it’s already held together for 52 years!The top is Spruce with an East Indian Rosewood back and sides. While conventional today, this is a large step up in materials for Yamaha at this time. Most of the lower line Yamaha’s were made of some variation of Mahogany, (Agathis, Sapele, Nato or other hardwoods), ending with Maple as the dominant “deluxe” build. East Indian Rosewood was limited to the top two models. Once again I have seen Jacaranda and Brazilian Rosewood claimed to have been used in the No.150 but it seems unlikely, as the grain pattern conforms to what you get in nice old East Indian Rosewood. Palisander has also been claimed but due to the similar grain pattern compared to Indian Rosewood this closely related species would be hard to prove, and less likely due to extra cost with little sonic or visual merit. It is however possible.The Fretboard is Rosewood, as is the bridge. The bridge tie bar is fully bound and equipped with a thin bone saddle. The guitar has been hand polished, the Fretboard conditioned and the strings replaced with new D’Addario Hard Tension Pro-Arte Composites. This set comes with a coffee colored synthetic G string specifically designed to prevent intonation issues and I find it works effectively on any guitar that does not have a reverse cut notch on the saddle. You can see it in this photo of the bridge.are the Specifications:Yamaha No. 150 Classical GuitarYear: 1965
