We recommend the Dampp Chaser – Piano Life Saver System as it keeps the piano at a constant humidity level year ‘round. It is installed on site and the system is hidden inside the piano. In addition to providing a constant climate and preventing rust in the strings and metal parts the Dampp Chaser allows the piano to hold better between tunings and minimizes felt deterioration and glue failure. Best of all, it protects your investment. For more information, please visit www.pianolifesaver.com Please contact us for a quote or to schedule an installation appointment.
