I'll start from the beginning. My ultimate goal is to simply record my bass using my SWR Workingman 15 plugged into my crappy Soundblaster Live! card on my pc. I just want to hear myself and play around with some software I have. My amp has two lines out, either the D.I. or the headphone jack. I went to Radio Shack and the music store that is next door to find out what kind of connections I need for connecting the D.I. to the Line-In on my soundcard. While at the music store, the clerk who acted like he knew what he was talking about said that I would be better off just running a cable straight from my headphone jack to the soundcard. He said the quality wouldn't matter. Fast forward to today. I finally get the cable necessary for such a connection, and in order to hear the sound on my pc I have to max the Gain and Master volumes. After five minutes of this, I smell a funny electronic smell. I turn around and there is smoke coming out of the headphone jack on my amp. I freaked out, unplugged everything and turned it all off. My questions to you guys are: Where did I go wrong? What's the worst possible damage that I could have done to my equipment? What are my options in terms of continuing this project?
