Buying Guide
1Test the weighted keybed thoroughly — weighted keys should feel consistent from low to high. Any dead or inconsistent keys indicate a problem.
2Check all audio outputs (headphone, line out, speakers) for crackling or dead channels.
3Digital pianos don't degrade tonally like acoustic instruments, so older models can be great value if the keybed is in good shape.
