Tasmanian Blackwood

Tasmanian Blackwood

 Tasmanian Blackwood (Acacia Melanoxylon) has gained incredible popularity among luthiers as a high quality guitar material for a broad range of acoustic and electric instrument styles. Tasmanian Blackwood timber shares incredibly close traits with the world renowned Hawaiian Koa (Acacia Koa) both in physical appearance and tonal properties.

Tasmanian Blackwood tonal properties are often compared closely to that of Hawaiian Koa but also Indian Rosewood or Mahogany. It is resonant, very projective, sustains tone and although it is a powerful Tonewood it maintains its smoothness beautifully.

Tasmanian Blackwood is predominantly a dark-chocolate brown with beautiful golden highlights that shimmer in any light. Colour in some cases can also be very rich golden colour with darker grain patterns. The beautiful shimmering of Blackwood fiddleback (curl) figuring is similar to fiddleback Maple and acquires a three dimensional property especially when finished. This species is easily workable, bendable and takes a finish that will gain much attention!

Our high standards in processing quality acoustic Tasmanian Blackwood is a timely task that often takes five years from log to guitar kit. Our methodology of log selection and quality control of each Blackwood flitch yields about 20% of the initial quantity, the remaining material being used in fine furniture.
