I had a similar problem which came and went unpredictably. I blamed the bass, got a new preamp and then it happened again, so I blamed my Markbass SA450.
As it turned out, it was a lead. I was just fooled because it didn't crackle like a lead problem. They were good quality leads and were nearly new.
I should have known better, but I was totally convinced it was the amp, until I bought new leads. It hasn't happened since!
It would be well worth trying different leads.
If it still happens with the new leads, try using one cab on it's own, if that works perfectly then I guess it could be the impedance.
You could always get an eden amp, they can handle down to 2ohms.[/quote]
Thanks for the suggestions.
I'm very tempted to go the route of getting an EA iamp since they should match well with the cabs (which I love) and I think they go down to 2 ohms too.
There may well be a Little Mark II appearing on the for sale section of this site very soon if anyone's interested. just make sure you're not using EA cabs!
Just out of interest how warm do Little Marks normally get when gigging them? When mine cut out it was quite warm and like I said I certainly wasn't pushing it; the master and gain were both only half way and that is far from clipping with my bass.
