Hey, let me start by saying this forum is such an amazing source of information which has answered countless of questions i had about serveral amp related things. Now that I've read that overpowering a cab isn't neccisarily a bad thing (on the contrary in some of your opinions), there's still one thing that keeps bugging me. My girlfriend has an Ampeg svt 3-pro running at 8 ohm (275w) going to a 4x10 hartke (don't ask) which is 200w at 8 ohm. Now this shouldn't really be a problem as long as she doesn't blast the master and graphic eq fully open. But sometimes when she's playing (she plays heavier music and with a pick), after a minute or 2-3, the amp just cuts out. I can't really remember the settings she dialed in but I was wondering if anyone has an explanation for this (the amp has been retubed a few months ago but i doubt that has anything to do with it)? One more thing, she's really hitting the pre-amp hard, but that should only increase the overal output (/watt) in a slight way right (since she doesn't really have the master full open)? Glad I now can also be a part of this community! Thanks, Robert.
