[Instrument Information]
This is a 2014 Class 1st (Hauser model) guitar, built with a 650 mm scale length.

It features a rich, full-bodied tone with a warm depth, complemented by expressive and colorful trebles. The instrument offers strong volume, quick response, and excellent sustain, with a well-balanced voice across the entire range. True to the Hauser style, it delivers a solid, grounded resonance paired with refined, lyrical highs. It is also forgiving to the touch, providing a high level of playability.

Finished in shellac varnish and equipped with Rodgers tuning machines. The neck has a standard profile and is straight, with minimal fret wear. String height is set at 2.8 mm (1st string) and 4.0 mm (6th string), offering a soft tension that enhances ease of play.

Now 10 years since its construction, the instrument is in typical condition for its age. Fine surface marks are visible across the top, consistent with normal use, but there are no major blemishes that significantly detract from its appearance. There are two patched repairs on the lower bout of the back; these have been properly executed and do not affect playability. The finish remains in good condition.
