unclej Posted February 2, 2006 Report Share Posted February 2, 2006 i had a customer bring me a fender blues de ville yesterday that needed a little work. guy plays the harmonica through it. after he described the symptoms he told me that someone had told him that if he replaced the 12ax7 closest to the power tubes with a 12ay7 that it would help eliminate some of the feedback problems that he was having because it would change the gain levels. i was honest and told him that i didn't have an answer but that i would find some info and let him know. so that's what i'm doing..trying to find some info. what would happen if he replaced just that one tube? thanks Quote Link to comment Share on other sites More sharing options...
