I was using my old Fender DR for a recording session a while back. The original speaker was in there. I kicked in my fuzz pedal, right then the volume went down to about half. A smell of plastic burning came on (but no smoke), so I shut it off right away. I let it cool down, then turned it on again...nothing, no sound. I brought it to a tech, who is always too busy, and left it there. After a while I contacted him and he said that he turned it on, and it worked fine. However, my speaker was shot and needed replacing. Do you think the smell was the speaker frying? Or, do you think that smell was some other component frying? I replaced the speaker with a greenback, and it is certainly darker sounding than it was before, so could it have been something else?
