I recently ran some pedals through the effects loop on the back of this amp to try out. Silly of me one of my patch leads was cheap and of poor quality and when I removed it the tip of the jack had come off. It is still lodged in the 'return effect' input and near impossible to remove without opening up the amp which is something I'm trying to avoid. I don't intend to use the effects loop but I'm wondering if this will in some way affect the sound. It's hard to say a I don't notice a difference most of the time but sometimes I do. An almost out of phase like tone. Now, this could very well be my ears and brain playing tricks on me because I know that the tip of the jack is still stuck in there. Can anyone tell me if it is possible this could at all affect the amps performance?
