Model D of Indian Rosewood and Sitka Spruce top.

Model D

Model D

The Model D is a modified dread.  The bracing patterned designed for this instrument gives the top enough flex for a great bass and a powerful treble.  The long scale (25.5”) pushes this instruments tone towards the fundamental, giving a crisp attack to each note and great cutting power.  The back is braced with three “fanned” braces that promote complexity of tone and minimizing weight.  Great in rosewood, for those playing bluegrass, or sapele for strumming Country tunes.

Model K Cutaway of Indian Rosewood and Sitka Spruce top.

Model K

The Model K is a mid-sized jumbo.  The bracing here is designed for maximum control in the mid and treble.  The shorter scale (24.625”) lends a lushness to the character and a forgiving attack.  Like the “D” the back is brace with three “fanned” braces.  This model is great in maple, giving a jazzy tone, where rosewood is great for fingerstyle.

Model R of Indian Rosewood and Western Red Cedartop.

Model R Cedar

Model R

The Model R harkens back to early days of American steel string guitars.  Based on a late 19th Century guitar, it is perfect for voice accompaniment of folk playing.  Similar in size to a “OO” it is comfortable to play and very responsive.  The bracing is light and spare, appropriate for the smaller size of the instrument.  Silk core strings really sing on this.  A fine choice in any wood.
