Hi, mates I have a 6 string guitar loaded with EMG 81/89. As of late I only play 7 stringers it stayed in its case for more than half a year. The other day I felt like playing it and after I plugged it, the sound started farting, bland, coming and going depending on how strong I hit the strings, but still utter garbage, unusable. I tried a fresh new battery in case the problem is the other is empty but the crappy sound is exaclty the same, as if the gain was off. What has happened here?
