Inspiration for the rosette

The inspiration for the rosette came to me, much like all my best thinking, while on an ocean-side walk. It was a beautiful sunny morning when I came across this rusty electrical part sitting on the rocky shore after the tide had receded. It was sitting upright, so when looking down at it I saw a vision of a volume dial. Back in the shop is when I could actually start pulling pieces of wire from the object. I scraped the coating that was on the wire due to sitting in the ocean. What I found was the wiring was actually aluminum, which could be used directly in the rosette. Now to actually create the rosette…
After doing a simple mock up rosette for Slash’s approval, I felt I could carry the theme of “electric” within the rosette design. This was done by running the aluminum wiring in a circular manner with simple “Rises and Falls” of the wire to create the feeling of energy, in a heartbeat monitor fashion, and encasing the wires with ebony, trimmed on the inside and outside of the rosette with “Fine (Pure) Silver.” To visually connect the rosette with the body of the guitar, I will be installing pure silver perfling inside the binding. It’s a very simple rosette. I am recycling the aluminum wire, yet due to the cost of the pure silver it is my most expensive rosette design to date.

Ancient Sitka Spruce

40 tonnes of soil was dug up to unearth this extremely rare Sitka Spruce that has been radio carbon dated to about 2850 BP = 3,180 calender years old. Born 1230 BC.Discovering the Ancient Glacier Sitka Sruce

It’s beautiful blue-grey colour is a result of soaking in the Earth’s minerals left behind by the receding glacier in which it was perfectly preserved for so many years. Ancient glacier Sitka Spruce top

As glaciers flow or recede, there is a mechanical grinding of the bedrock below, which produces glacier flour, or glacier silt. These fine-grained, silt-sized particles of rock are rich in minerals and depending on the type of rock, will produce colours ranging from grey to blue to green. You may have seen this effect in various mountain lakes and rivers.

JOI Guitars is excited to be in possession of 5 sets of these ancient Sitka tops. The tap tone of these tops produces a deep, resonant bass with a clear high finish.
