Sitka spruce

Sitka spruce has an excellent strength to weight ratio and for that reason has been used in making sailboat spars and parts of aircraft especially before WWII. This high ratio is also great for making musical instruments and I like it very much. I have made a few guitars already with this top wood and I find the results are excellent. The rosette design comes from my teacher Rolf Eichinger and has been used by a few of his disciples. I have quite few Sitka tops which I bought in 2001 or thereabouts from Timbre Tonewood in British Columbia.

Yew Tree

As I almost always do, I spent Christmas with my wife’s family in the north of the province of Granada in the village of Castril. The mountains and the river valley there are nothing short of spectacular and a great place to explore. The photos show a yew tree which is said to be over a thousand years old. I have never used yew for instrument-making nor have I ever made a longbow. It seems that the English preferred this wood for their bows and there are a lot of references to yew used for lute bowls. I had a good look at the tree and I certainly would not choose this as a tonewood. Lovely tree though.

Wormholes

Who wants a guitar made with this back? Should we use wood with wormholes? Obviously it is ecologically more advisable to use it than to discard it or burn it. My teacher used 3 and 4-piece backs and wood with wormholes to make some fantastic guitars. No one seemed to mind. I don’t buy endangered rosewoods since the ban on D. nigra and since I heard about the situation in Madagascar. The other question is: Should the holes be filled and “hidden” or should we proudly show that we are creating beauty using flawed materials? Filling the holes is probably better for structural integrity and acoustics but it can be done in such a way that draws attention to the holes or not. There is a danger too that filling a hole will create a super-hard foreign object which can cause a crack when the wood shrinks around it. One of the old guys here used to take the wood and cut vertically where the holes or defects were and then glue it together again. I saw some of the results of this on his spruce tops and it was invisible. Maybe the question should be: Do you prefer something like this or alternative non-tropical woods?

It is worth noting that any holes you see in rosewood were likely made while the tree was living so if you buy wood or a guitar with wormholes you are probably not importing bugs or eggs into your shop.

My Guitar at Galerie des Luthiers

I enjoy showing off my rosette work but without a doubt the best ones are the historic copies or a few one-offs I have made. I have an idea how to improve my signature rosette but I don’t know when I will get around to that. Here is an example of a change that I tried and now I have to decide if I like it better or to go back to the old version. In the version above I doubled up the centre line to make the black a bit stronger. Below is the rosette that I have used for my concert guitar on close to 200 iterations. By the way, the guitar in the video is for sale.
