For those that HAVE pushed the Compact into compression...

Firstly, is there an 'Overload' light, so you can TELL if the compression/limiting circuitry has kicked in, and what does it sound like? Is it easy to hear, or well disguised?

Even if you can't blow up your Compact, having a limiter effectively 'duck' your signal every time the kick (or whatever else is too hot) hits can't be that good for your sound, can it?
