Hello! I recently got my hands on a brand new swan concertina, and I am loving it for the most part, only I've been noticing that the 2a button makes a crackling sound on the pull. I don't really have any knowledge on instrument repair, so I was wondering if anyone could tell me what might be causing this?

Hello everyone! I haven't been able to find tabs for Bosun Bill from Sea of Thieves anywhere on the internet, does anyone know of any tabs for this song? I could try sounding it out, but it's difficult for me to accurately piece together the lower harmonies, as they move pretty quickly. Thanks for any help/advice!
