Allright I'm at home by myself and I figure I'll go in the basement and do some playing. I have one 18 watt combo on and on standby and one 30 watt Tweed combo on standby and one Mesa Boogie Lonestar Classic on. The Lonestar is cranked with the master wide open and the drive knob allmost all the way and the channel gain allmost all the way and a freakin Boss Blues Driver on and I was Jamming like a fool. Amp set for 100 WATTS ss rectifier. So I had that little 1x12 combo Craked! The next thing I know there is a Major puff of smoke filling the room. WTF! I'm pretty shure it came from the LS only because it was cranked so I shut every amp off and did some looking, I couldnt find anything on any amp hot except Tubes. Checked speakers, trannies,etc... Turned each amp on and tried them with no problems. Tried the Lonestar again cranked and had no problems. Played it for a while like that with no problems. Again WTF? Its clear it was an eletricall smell and when I came upstairs smelled it all over the house. What gives? When I first noticed it was when it bellowed (visually) over my head. Then I smelled it. Whats going on here?
