I use limiters as a safety valve and never just to raise the apparent level of anything. Not into that kind of thing and certainly not in the realm of Death Magnetic. BTW Lars did acknowledge that he was the cause of that overblown mix engineering for what he told the engineer to do.

I use a limiter on my drum bus - actually I have two drum busses. One that collects all the feeds from the individual tracks which feeds a second drum bus and has a send to a separate drum verb track which returns to drum bus 2. Both busses get a limiter. Either Pro L2 or the SSL Limiter. Yes I have others but they don't get used.

My other use for a limiter is on my 2-bus and that's always Pro L2. All my limiters are set at either -.2dB or -.5dB.

Compressor on the 2-bus. That can be the SHMC green or red and sometimes an SSL bus comp emulation. Compressors on tracks and busses as needed but ONLY as needed. Just like eq's I don't put compressors on everything.

Clippers - NEVER! Just not my cup of Earl Grey (hot).
