no sound will come through input

@james33 since the other input works, you will have to take your amp apart. Check to see if the jack is still properly connected to the circuit board. It is possible that the jack does not close the circuit when you insert a connector. To take it apart you most likely will find that you have to remove the back as well as in some cases the carrying handle. All your controls will be a one single board in the upper part of the amp. Take plenty of pictures and post those with your question so that we can see what you see. 기존 질문에 이미지 추가하기
