Not with the Mbox but I do have a several RNCs that I use on guitars and sometimes vocals. Ugly looking little beasts unless you rack them up in the Funk Logic rigs or something similar but they do a very nice job for the price. I haven't tracked a bass through one but as long as you don't set the attack too fast it should be fine. As for comparing to PT plugs that's a little more complicated. Two different animals, in the box digital (PT plugs) vs out of the box analog (RNCs) with potentially different applications.

All in all not bad little compressors (especially in that price range) if you just need a little taming before the DA converters or a little glue coming out of the stereo buss. Just make sure you understand what you're getting, i.e. stereo (not dual mono) channels, no balanced ins/outs, etc. The online literature is pretty clear about the details.

Hope that helps some,
