I have to play an outdoor gig tonight and it is forecast to be 5 degrees Celsius (41 Fahrenheit). I will be using my Shen 7/8 Willow flatback. Ive never played in weather that cold before and normally would not think of taking my bass out. Im a bit worried. It should be plenty humid as it has been raining here a lot and it is generally humid in summer. Of course this is supposed to be summer but weve had freaky weather here lately. Should I be concerned?
