I know its just another feedback question you guys are thinking. But I looked at all the other threads on here and they all ran through pedals. I dont run through any pedals just my guitar straight into my amp. And theres no hum while im playing. But as soon as I stop playing at volume makes this high pitch sound unless i turn my volume on my guitar off and then it like makes this scratchy hum noise at thats low volume. Im running my RG7620 with stock pickups into a Randall RH200G2 into a H&K Warp 7 cab. And I have played through other power sources because I just did a show with it at school and it did the same thing there. How could I fix this problem without spending too much money?
