The title pretty much says it all. I installed a SD STC-2C-BO 2 band EQ in my Squier VI. For the first year batteries would last 3-4 months with daily play. Now no matter how much I use it or don't the battery only last about 2-3 weeks. I've looked inside the control cavities and nothing jumps out at me, how do I trouble shoot this. It's got to be a short somewhere right?
