He is talking about the power amp limiter, not the 'input limiter/compressors' that some heads, like the RH450, have.
Yup. Exactly that.
I'm rather fond of the sound of it, but it takes a good bit of cranking to get there. I'm guessing I might get there a bit sooner with some EQ boosting, but perhaps an outboard peddle may be a better option there. I just don't know how close an effect peddle might get to that sound.
BTW - Sorry for the thread derail. That 9.0 looks pretty sweet!
