The Weinbach brand has been an essential part of PETROF‘s portfolio.

Weinbach 128 Z3

This piano is especially suitable for elementary music schools or as an accompanying instrument for singing and recitation. Thanks to its height, it has a very good sound potential and can serve well wherever the grand piano does not fit.

The Weinbach 128 Z3 is characterized by a taller cabinet and a larger acoustic element that creates a rich, powerful sound. The use of appropriate materials will ensure stable playing and interesting tone color that will delight even an experienced pianist.

The piano is manufactured by our foreign partner. Finishing operations, including inspection, tuning, and voicing, are performed by experienced PETROF employees.

The Weinbach 128 Z3 piano represents a great price-performance ratio. The warranty service of the instrument is provided by experts from the PETROF company.
