Jackson Guldan was a US company out of Columbus, Ohio that made a whole lot of violins and some well constructed parlor sized guitars that had a unique neck setup - the angle can be adjusted anytime by turning a small inset screw at the neckjoint. - With that adjustable neck, 24' scale, and a trapeze tailpiece it makes it a good choice for double tenor conversion - Chicago style - tuned to DGBE.It can also be played in Irish tuning, GDAE, with larger strings - same as an octave mandolin. It's tuned like a regular guitar with just the first 4 strings. The action is good, bordering on sweet - string height at the 12th fret is 3/32" bass side, 1/16" treble. The acoustic quality is something else - has to be heard. I've posted a sample on SoundCloud under ClaytonAudio. Ships in a new padded gig bag. Length - 36" Scale - 24" Lower bout - 13" Upper bout - 9 1/2" Nut - 1 5/8 Weight - 4.5 lbs.
