Hello!

Love My sylplyo. So much that I am scared to damage the sensor by trying to clean it.
What do all of you recommend to clean? I can't seem to find a cloth that will easily fit towards the bell. Afraid to use swabs as they tend to leave fibers behind.
Is there a good tough swab that I can use? Was thinking of wrapping a thin rod with soft cloth and gently easing it in and out to clean.
Also, should I clean it every day? New to thee instruments. Thank you for any info.

Hi.

Just wanted to introduce myself to the community. I am a bit freaked out as I decided to get the Sylphyo after looking at info for only a few hours, but it look likes EXACTLY what I have wanted for so long- an instrument that converts breath or voice to different instruments. I have also been searching for an instrument to learn as I am a song writer and sing with a band but also felt I could do so much more when creating music if I could learn to play something. Well, I am coming to this wiht barely any wind instrument playing at all.
I am a bit scared as 1k is a big investment for me- got the link bundle - , but I am more excited to see what I can do when it gets here this week!
One question if anyone can reply - I am in the U.S. - do I need t purchase a wall plug adapter and if so, which one would I need? Thanks in advance!
Anyway, looking forward to interacting with ll of you in the future.
