Card I have the 3rd edition of the Piano book, here's the review of the piano you described-
"The Classic series of grand, introduced in 1989, consists of the model B1 (4'10") and model C (5'7"). Baldwin's intention here was to offer a more simply built product to compete effectively with low priced imports, with fewer features and less attention to detail thanin Baldwin's regular (Artist)line of grands, but appropriate for the more casual user with a limited budget. Though the intention was certainly a reasonable one, the execution thus far has not been satisfactory. In fact, in the ten years I have been reviewing pianos, I have never received more negative feedback about a line of pianos than I have about this one. Hardly any aspect of these pianos remains immune from criticism, as these comments from one experienced technician (and echoed by other illustrate: 'Characteristic of this model is a very pinched, whiny, nasal tone with very little sustain and vague, wavering beats throughout most of the scale....All of this makes tuning, especially unisons-very difficult and annoying....The sound is what I would expect if there was a wedge driven between the soundboard and the plate. The Piano seems to have an endless capacity to drop in pitch. After six tunings in eighteen months, every one is still a major pitch raise.' "
One other tip- if you're buying a used piano, you can sometimes find an older copy of the piano book at your local library that would have a review of the piano when it was new!
Good luck again Card!
