I don't know why, but when i strum down, it doesn't work. Whether i'm trying to select something or strumming notes, it just does nothing at all. Please reply if you know something that will help or if you had the same problem. Thanks.
If this is a new guitar, return it for a replacement or contact the manufacturer. If you have had it awhile and you beat up on your strum bar like I do, this will happen every now and then. I have had a great deal of luck with the replacement strum bars made by Byte Arts and they have good customer service as well. Here's a link to Strum Fix Plus
