Question, Is it ok to let the bass head stay in the car overnight when the temperatures are in the 20's...winter time. I bring the bass guitar (Fender 1957 P bass copy lawsuit model made in Japan by CAMEO) inside the house, yet I leave the bass head and speaker (Yorkville, Made in Canada ,15 inch celestion driver), in freezing car. It this Ok??? I probably should bring it inside, yet I have gigs 2 or 3 days in a row. Any insight will help me.....Thanks king koeller
