Hello, I just purchased and received my first Variax (Standard) Sunburst. First of all, it's a beautiful guitar and plays very well and feels great. I bought this guitar because I really needed a guitar that I could take to a gig and have so many different guitar types and tuning available like I'm sure many of you are thinking alike. Well, I was getting to know my new guitar absolutely stoked out. It played good for about 3o minute then it made a quick screeching sound and I just shrugged it off as it is working with some complex modeling systems and I kept playing. Well, maybe 10 to 15 minutes later this large airy noises started coming out of the guitar. When I turn the modeling system off and just use the regular SSS (Single-coil) system it fine but every time I push down on the modeling pot to on that guitar modeling system it starts that airy sound again. It's pretty loud and something I can't get by with. I also notice the 4th string (D string) is quite softer then the rest. I guess a new set of strings and setup might help with that but I'm totally bummed out with the noise problem. Please anyone of you can help me please let me know. I'm thinking that this could be a common situation but not sure. Much aloha from Hawaii and mahalo (Thank You) in advance.
