Ash that is referred as “Swamp Ash” is a light-weight porous wood that comes from the swamps of Southern USA. What comes from a tree that grows partially engulfed in water is an intriguing formulation of hard and soft lines in the ring of the tree. The resulting tone of Ash is what people usually call “bell-like” because of its detailed high end and excellent dynamic range. We all know that Fender used Ash in the 50’s to produce some of the greatest Telecasters in history. The ultra light nature of this striking tonewood helps the guitar to sing and twang like no other. In general, swamp ash retains a very dynamic character along with strong lows and nice balance of warmth and bite.
Northern Ash is a denser, heavier species of wood that will have more sustain and an even brighter tone. However, the mass makes it less snappy than the lighter swamp variety. I should mention that every body varies just as trees do in nature. On top of that, a wide variety of species exist of these types of wood around the world. So you might find a heavy ash body or dull piece of alder. That’s why it’s a good idea to get your hands on a guitar and plug in before you buy.
