Like many, I find in the Summer months here in the Northeast we play a lot of outdoor gigs. This past Saturday we played a festival and it was in the 90's and very humid. I've always been aware of the issues with strings and the back of the neck under these conditions but, this particular event was the worst I recall. I found I was fighting the neck and strings more than usual. So, I got to thinking about this to try and come up with a solution. I thought something like Fast Fret or similar product might work for the strings. But, was wondering about the back of the neck. My first thought was light powder in the palm of my hand. I'd love to hear what has worked for others along this line. I'm convinced I have not thought of all the solutions. Thanks!
