That kind of detail really helps improve the quality of the transcription. The missing word being “plectrum” makes perfect sense in that context, especially when talking about strumming without a pick. It is easy for automated or rushed transcriptions to miss specific music terms like that. Hopefully someone Rabbit Road Inout on the transcription team can update it soon. Small corrections like this make a big difference for people who rely on subtitles to follow along. Good catch, and thanks for taking the time to report it.
