These two instruments are the same one and should probably be merged:

• Guitaret https://musicbrainz.org/instrument/cc161ccd-7116-44cb-be69-cb7bb965b914
• guitaret https://musicbrainz.org/instrument/9465df95-c901-4402-a169-7005756fdcaf

The correct data is a mix of both:

• name: Guitaret (with an upper-case since it is a Hohner series)
• type: Electronic instrument (rather than Percussion instrument)
• description: both are correct and incomplete, let's merge them:

  a small white electric thumb piano with metal tines and an electromagnetic pickup made by Hohner.

By the way, the same capitalization rule should probably be applied to the other Hohner series too:

• cembalet → Cembalet https://musicbrainz.org/instrument/2cd8f5f1-0c0e-4a7e-92f3-14e795473a3b
• clavinet → Clavinet https://musicbrainz.org/instrument/563a9f16-e84b-409a-bda5-2e4ce09d5573
• pianet → Pianet https://musicbrainz.org/instrument/0e229ccc-5fea-45f5-8efc-abc6c1c17dea
