This Guitar, serial No. CrossO-TBW001, made by hand using the materials listed below
Back and Sides - Tasmanian Blackwood (Acacia melanoxylon)
One of Australia’s best-known Tonewoods, used both domestically and internationally.
This Tasmanian Blackwood has some stunning compression figure.
Back Bracing System - Live Bracing Design
This system increases the backs interaction with the soundboard during playing, resulting in a fuller more complex sound. The Bracing has been made to fit a 20ft Radius, which increases the stiffness and structural integrity.
Soundboard – Western Red Cedar (Thuja plicata)
As a tonewood, Western Red Cedar was "discovered" relatively recently. Over the last 30 years Red Cedar has gained tremendous popularity. Well quartered Red Cedar offers exceptional tonal quality. Although the wood is less dense and softer than Sitka Spruce it produces a crisp balance of sound. This set exhibits all those qualities, plus it is multicoloured, displaying all the colours that Western Red Cedar comes in.
Soundboard Bracing System – “Carbon Fibre reinforced Falcate.”
The soundboard bracing system has been made to fit into and was assembled in a 40ft radius dish, which increases its stiffness and structural integrity. The Carbon Fiber reinforced Falcate (Sickle shaped) Bracing is made of strips of King Billy Pine, laminated into sickle shapes that are radiused to 40ft. There’s a layer of Carbon Fiber between the bracing and the soundboard. The Bracing tops were profiled, and another layer of Carbon Fiber put over the top, effectively making an “Í-Beam” like structure. This radiused and curved symmetrical bracing system is of low mass and is incredibly stiff.
Bridge, Headstock and Fretboard - Ringed Gidgee
Tuners – Custom Built by Rubner of Germany,
Gold with engraved plates and Rosewood Buttons. Exceptional High-quality tuners and recognized as such around the world. Rubner was founded in 1864 by Josef Rubner, as the first machine centre in Markneukirchen, Germany. The Company is still family owned, now run by Hans-Thomas Rubner a 5th generation Rubner, and still using some of the century old machinery.
Neck – Tasmanian Blackwood (Acacia melanoxylon) with a Gidgee Spine
Deeply figured Tasmanian Blackwood with a Ringed Black Godgee Spine
Fretwire – Jescar Evo-Gold
Rosette will be an Open Composite Design...design TBA
(Headstock, 12th Fret) – New Zealand Paua Shell (gold tint)
(Haliotis iris or austalis)
Paua is the Mauri name for Abalone. While the name Paua is used extensively in NZ to describe any Abalone collected from NZ waters, in the Luthier world Paua usually means it’s the predominately blue abalone that comes from the south end of New Zealand’s South Island.
All shell on this instrument was sourced from “Ocean Shell” https://lumea.co/about-us/who-we-are
Nut & Saddle – Hand made from Northern Territory Buffalo Horn (Syncerus caffer)
The 6mm saddle is a firm fit into the Bridge but can be removed if needed. It has a line scribed along the soundhole face; this indicates the orientation of the saddle in the bridge. The Nut has been slotted to suit the as fitted Strings. The Nut is also a firm fit; a small amount of CA glue has been put under it to hold it in place while changing strings.
Strings – D’Addario Pro-Arte Dynacore EJ45TT
Even though this instrument has Carbon Fiber Reinforced bracing, it is not recommended to increase the gauge of string from that as originally fitted.
Pick-up System – TBA
Finish - High Gloss Nitro Cellulous Lacquer
A hardwearing lacquer that is chemical resistant and easily repaired. Approximately 20 coats of Lacquer are applied over a 10-day period, after a week curing time, the lacquer is hand levelled using wet/dry sandpaper, micromesh pads and finally buffed to a mirror finish.
