We based the T20HGc on our successful T20Ac Auditorium Cutaway six-string, giving modern harp guitarists a hollow arm harp guitar with easy access to the 20th fret. We experimented with bracing to come up with a robust instrument that would yield great tone: a balanced neck, seamless transition from the low neck E to the first D sub-bass, all the way down to a killer low octave E.  The tropical mahogany solid top not only looks great, it sounds sweet and smooth.  The tapered body ends up over 4-½” deep at the end pin to give extra power and growl to the sub-basses, while the neck is a standard Timberline, with the comfortable 24.9" scale and 44mm neck width.
