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

Weinbach upright piano 128 W2, with its stable construction, is suitable for intensive use, for example in school. The upright piano is equipped with PETROF action and RENNER hammerheads. The instrument is produced in cooperation with our partner, with whom we have been working since 2013. In his workshop, the acoustic element of upright pianos, including cabinet assembling, are made. We completed the installation of the action, regulation, tuning, and voicing in PETROF in Hradec Králové.

It‘s a reliable instrument with a rich, elegant tone you‘ll fall in love with. Another advantage of this Weinbach limited edition upright pianos is their favorable price.
