A variation on the "classical" guitar, combining elements from models with steel strings. The brace construction is based on a classical guitar, but the wider fingerboard has a similar radius like the steel string guitars. Also the neck uses standard truss rod with the possibility of easy adjustment. For these instruments we use models (body shapes) OM or GA. The neck joint is usually fitted on the 12th fret with a scale of 648 mm. A variant with a standard 14-fret neck is also possible.
