I think the point to be concerned about when choosing a used piano is "how much has been repaired".
The impression is quite different depending on whether it has been adjusted as it is or whether it has been partially replaced.
This time, the Kawai KL-801 piano arrived, so I replaced all the strings.
Using this KL-801 as an example, I will explain the advantages and disadvantages of "already replaced strings".
