| Humidity number is a bit low but doubtful it'd hurt it. My stuff goes from 45~50%(indoors at home) to whatever is outside here in south Texas...at least once per week for 5 hours or so. Humidity here goes the other way, it's usually high(70~95%)...or it's raining.
If you had a $30,000 upright bass it would probably be a concern.
PS:Our houseband gig is outdoors on a covered deck adjacent to a resteraunt and bar.
Gear's been doing this for years.
