Ringed Budgeroo Mandolin specifications
Gladstone Mandolin “Ringed Budgeroo 001”
An ‘A’ style Mandolin with a scale length of 352mm and 12 Frets to the Body. This Mandolin
S/N - Mando-RBUD-001 2026 was built by hand using the materials and methods listed below.
This instrument is a combination of Flat Top and Carved Mandolin design. The soundboard top is carved, but the underside is flat. Neck angle is set higher than a flat top instrument.
Back and Sides - Ringed Budgeroo (Lysicarpus angustifolious)
The genus of Lysicarpus described in 1858, has only one member, and it’s endemic to Queensland, Australia. “Ringed” refers to fiddleback type grain structure and is quite rare within the species. The trees with ringed grain are always small but are always visually stunning.
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 - Alaskan Bear-Claw Sitka Spruce (Picea sitchensis)
Sitka Spruce has long been the standard sound board material. The Bear Claw pattern is unique to each piece and gives it a third dimension.
Soundboard Bracing System –Carbon Fibre Reinforced ‘H’ Bracing
The soundboard bracing system has been made to fit into and was assembled in a 20ft radius dish, which increases its stiffness and structural integrity. The rectangular cross section Adirondack Spruce Bracing is installed over a layer of Carbon Fibre. The Bracing tops are then profiled/carved/tuned to give the desired stiffness gradient across the soundboard, but still maintaining the rectangular cross section. A second layer of carbon fibre is then installed down the middle of each brace, this effectively turns each brace into an ‘I’ Beam, greatly increasing its strength and rigidity. The braces are then carved into a triangular cross section, which decreases their mass but not their strength. This radiused, CF reinforced symmetrical bracing system is of low mass and is incredibly stiff.
Headstock and Fretboard- Ringed Gidgee (Acacia cambagei)
Gidgee is considered a pest plant by farmers, sometimes referred to as Stinking Wattle, but it is perhaps Australia's hardest wood. It has tight interlocking grains, making it ideal for these applications. “Ringed” Gidgee is the curly grain form, it can be visually stunning and is considerably rarer.
Tuners - Gotoh Baby 510 series in Gold with Ziricote buttons
The smallest closed gear tuners, made to order in Japan and are of exceptional high quality and recognized as such around the world.
Adjustable Floating Bridge a “Brekke Bridge”
An Ebony Floating Bridge with a height adjustable saddle. The height can be set using the supplied 1.5mm Allen Key.
Neck - Queensland Maple (Flindersia brayleyana)
This is a 3 piece Neck, having a Ringed Budgeroo Spine. Queensland Maple is perhaps Australian’s Best Tonewood. Highly sought after by Australian Luthiers. Heartwood ranges from yellow to golden or reddish brown, darkening with age. Narrow white sapwood is differentiated from heartwood. The grain is interlocked and sometimes wavy. Texture medium to coarse with a good natural luster.
Rosette & Headstock Triquetra – White Pearl
This rosette and Headstock inlay are made of White, ethically sourced from New Zealand
Nut–Northern Territory Buffalo Horn (Syncerus caffer)
The Nut has been slotted to suit the as fitted Strings. While the Nut is a firm fit into the slot, a small amount of CA glue has been put under it to hold it in place while changing strings.
Tail Piece– Hand Made Brass
The 1.2mm Brass tail Piece is designed to accommodate either Loop or Ball End Strings. It’s been polished and coated with pre-catalyzed lacquer.
Strings – D’Addario Stainless Steel EFW74
Medium gauge flat wound stainless steel mandolin strings. Flat wound mandolin strings deliver a smooth feel and full tone preferred by classical, jazz, and bluegrass mandolin players.
Pick-up System – This instrument does not have a pickup,
However, it is pickup ready, having an output jack compensation block fitted in the lowerbout
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.
