That's when you get water (assuming you have water) to freeze,= =20 right? Thought so. Yeah, I've seen it before, but... it's never EVER been=20 something I've had the opportunity or desire to study. <G> Sorry, no words of experience or wisdom to impart for this one. If it's a=20 solo concert, then.... why worry? Float the pitch, maybe, 'cause you're=20 sure not gonna be able to predict the change. I imagine that the spotlight= =20 might have a little less of an effect due to the severity of the ambient=20 temp, but... whew... too hard to guess. Just remember, it's the strings.=20 Not much else matters. So... if you're really concerned, pre-light (20=20 minutes) or keep shaded. Either method will slow down the changes during=20 play. I guess audience BTUs won't have much impact! Good luck! Regards, Guy Ft. Stinkin' Desert (where there be no ice) P.S. BTW the "formula" is basically .8=A2 per degree F. . Many other= factors,=20 of course. Special thanks to Don Gilmore. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
