An extended range 7 string guitar, the Gary Kramer Turbulence adapts the Delta Wing’s swoopy body shape to accomodate the instrument’s range.
According to the site, these changes include an enlarged lower body scoop and a redesigned sculpted neck heel area.
Also noteworthy is the use of two fret sizes. Medium jumbo frets are used for frets 1-24 and skinny tall frets are used from 24-36 in order to “achieve better fret spacing in the hyper range.”
The Turbulence also retains the removeable left leg rest unit which you can see used to excellent effect in this video clip of Livio Lamonea playing Dream Theater’s Another Day solo. Note the guitarist’s relaxed and neutral sitting position.
The Delta Wing and its offshoots make for an unusual design that could make some inroads with the rock and rock fusion crowd.
