Who in their right mind would schedule an outside event in that temperature? Must be an ice carving or snowman building event :-) Any instrument, not just the bass, will have problems.
Having owned a Ric before......I can say I love the way they play and sound. However, they are way overpriced now and IMO not worth the premium. Much like some of the more expensive Fenders.
If your intent is to get it sounding like a Fender Jazz, you'd also have to install Jazz wiring harness and pots. Even with that it wouldn't mimic the Jazz sound completely. IMO
