This concert upright is the acoustic equivalent of a 180 cm (6 ft.) long salon grand piano, awarded ‘Best in the World’ in Paris. Universities, small concert halls, and churches alike use them in place of a grand piano.It comes equipped with our classic action and enhanced chamber-music dampening for the single string sections as standard.
The basic models are:
- 138 K with the classic Steingraeber action, as a smooth alternative for music lovers and a joy to play
- 138 K-SFM with Steingraeber-Ferro-Magnet Action
Additional options include sostenuto pedal and enhanced chamber-music dampening for the 2-string bass section.
- two alternative action systems:
„classic“ or „SFM®“ for 1mm repetition point like grands (both Steingraeber-Renner parts)
SFM = Steingraeber-Ferro-Magnet
