The instruments need to be either playable, or repairable.
For example a violin which needs new strings will be ok, but one with a broken neck will likely not. Please use your judgement and keep in mind that we are a charity. We want to use our resources on placing instruments in new homes, not repairing badly damaged instruments.
We are accepting donations for instrument repair, so if an instrument is damaged but repairable please either get in contact with us or send it in so our experts can assess it.
