As most persons know, this winter has been very severe in the South (I live in south Louisiana).
In my opinion, Music Sorb has definitely helped maintain the tuning of my instrument, and I would recommend it to anyone with a piano who cares about protecting the long-term value of the instrument.

Vertical and Grand Pianos Humidity Control System Setup

Music Sorb+ cassette
Installation of Music Sorb+ in a Grand Piano
Open the Mylar covering and slip the cassettes out. Be sure to write the date of installation on the tag we provide, so you will be sure when it is time to replace it. Finally place them in the grand piano.
The most convenient place to put one MusicSorb+ unit would be on the metal plate of the piano at about the point where the rim of the grand piano curves toward the treble end. Then place the second cassette further down toward the tail of the grand piano but close to the rim. Don’t place them on the sound board because they would impede the movement of the sound board and might be inclined to rattle.
MusicSorb+ will be most effective if the top of the piano is kept in the closed position. MusicSorb+ will function for a two year’s time, then you will need to replace it.

Installation of MusicSorb+ in a Vertical Piano
If you purchased cassettes for your vertical piano, you open the Mylar covering and slip the cassettes out. Be sure to write the date of installation (or expiration, if you prefer) on the back of each cassette and then place them in the piano.
We advice to place MusicSorb+ inside the vertical piano behind the knee board. Most knee boards are held in place with one or two clips that are attached to the underside of the keyboard. Slip the knee board out of the way and place the two cassettes in the bottom of the vertical piano. Be sure you can see the date of installation (or expiration) on the MusicSorb+ cassette. Then put the knee board back in place and that’s it, you have successfully installed MusicSorb+.
MusicSorb+ in all of its variations will function for two year’s time from the time you open the Mylar bag, then the cassette will need to be replaced.
