Just opened a brand new 89 today. While I was charging up the battery, I played the guitar with the mag pickups. All was fine, sounded great. When the battery showed full charge, I put it in and it showed four green led's. But no sound anymore, not the magnetics or the models. I took out the battery and the magnetics worked again. Put the battery back, held the Model buttton down while inserting the 1/4" jack, nothing. The guitar refuses to work with the battery in. I opened a ticket, but was hoping maybe you guys might have something to try. Thanks
