The Tanglewood TW40 D AN E is a dreadnought electro-acoustic guitar offering beautiful tone and fantastic plugged-in performance. Each guitar in the Tanglewood Sundance Historic series has been carefully designed to offer authentic tone and fantastic character by master luthier Michael Sanden. As a result, the Tanglewood TW40 D AN E is a beautiful guitar in every sense. Solid Spruce has been used for the top of the Tanglewood TW40 D AN E. Spruce is a very sought after wood in acoustic guitar building due to its high tensile strength and flexibility making it very versatile. Also, since the Tanglewood TW40 D AN E features a solid top, it'll sound better with age as the wood becomes more resonant and full of character over time.
