The Takamine Natural Series was conceived to give you the biggest and widest acoustic sound possible. Solid cedar tops, solid mahogany backs, a thin satin finish and no pickguard - anything that could possibly impede the vibration of the soundboard was purposely left out.
The theory works. Naturals are so alive with sound that they nearly jump out of your hands. The clean and simple approach of the Naturals has been imitated by other makers, but nothing yet has compared to the purity of style - and sound - of the original.
