I was a woodworker for many years and I am familiar with different types of joinery, choices of wood, cuttting and gluing tolerances of less than 5/1000 of an inch, the perloid inlays on the fretboard are set perfectly. Upon close inspection this guitar is almost flawless, this guitar left the factory with all of it's quality control measures firing on all cylanders. The action was too low, on inspection the saddle may need some adjusting, the 1st and 2nd string hang a tiny bit lower or higher than they should and do not match the radius or curvature of the other strings. I will contact Thomann for advice or a new saddle.
The size and feel of this jumbo is a little bit smaller and more comfortable than some I have tried. I am a senior [75 yrs] played many types of guitars, mostly classical, for 60 yrs, I am 5' 7'' and 165 lbs with smallish hands so this was a bit of a risk taking on this large a guitar at my age. It sits well on my lap and standing with a strap fitted high on my chest lets my strumb and finger pick with ease. The tones produced by the body chamber are very rewarding, grover tuners, fishman pre-amp with tuner/phaser, upgraded D'Addario strings and solid wood top, excellent poly finish etc, etc... the mustache bridge reminds us of a mostly unafordable guitar that this Harley Benton seems to match by many standards. I recommend this guitar.
Four weeks later: changed the nut, saddle and string pins with special order bone products, cleaned the fretboard and changed strings to D'Addario 10's. The new saddle fixed the radius problem, lighter strings easier for me to play, gently filed and lubricated new nut and the bone pins seemed to add a new brighter sound. Very pleased with this simple upgrade.
