As you can see she’s turned out very nicely; the English walnut has polished up wonderfully.
There are a couple more Parlour guitar videos on YouTube covering the design of the back and the soundboard.
Now of course many luthiers like to shroud their work in mystery and would never divulge the secrets of their soundboard! However, I’m quite happy to share my knowledge with you. I’ve been fortunate to meet many world-class luthiers and in my experience it is those who are confident in what they do, who are willing to help others and advise. Someone may well copy my design, but I’m a great believer that a guitar is greater than the sum of its parts and the influence of the hands that made it, have as great a part to play as the strutting pattern or choice of tonewood.
I find some of the threads on guitar forums both amusing and irritating; many players and luthiers (who should know better) will debate ad infinitum the merits of Dalbergia Thingamajig versus Dalbergia Thingamabob or whether bone bridge pins produce a better tone than ebony etc. You can’t just take one element of an instrument in isolation and assume it’s that element that makes your guitar superior or assume that because you tried out a wonderful guitar made from 35000 year old Kauri tonewood that all guitars must be made from this. Beware of forums!
