Hi Sarah, it depends on the model and year of manufacture. Grinnell Brothers was a Detroit-based company that manufactured pianos from 1902 until around 1960. They had a good reputation. The name has since been acquired by Samick who has pianos built abroad and puts the Grinnell name on them. I haven't any personal experience with this recent product. My late mother played for years, from the early twenties and into the nineties. Her piano of choice was the Baldwin Acrosonic. You might want to consult pianists, piano teachers and piano tuners. Just as a matter of interest to any history buffs, the Grinnell concern opened a number of music stores in the early sixties in the then-new shopping malls. These stores were a great resource for instruments, sheet music, records, etc. They always had private rooms where you could try out various instruments. These stores closed down in the late seventies. The original headquarters for Grinnell Brothers still stands on Woodward Avenue in Detroit. It's a truly grand piece of archiitecture based on the Chateau de Chenonceaux in France. Anyway, good luck with your piano shopping.
