The RNC is indeed a strange agent but does work well with bass...provided you make some unusual adjustments. FWIW, FMR actually understates the RNC's capabilities in terms of attack and release. Using suggested settings (attack - 6.0 msec, release - 1 to 3 sec), I found I was getting a nasty distorted tone. The general philosophy has been to increase release time until the distortion disappears. No luck! I then tried increasing attack time to a minimum of 20 msec (sounds like a lot, doesn't it?). Bingo...worked like a charm. This is a great starter setting as it provides smooth, almost inaudible, compression without swell or "pumping / breathing". Want a little more "squash"? Daisy chain the output of the left channel into the input of the right; right output to your amp. Gives it a double-dose without sounding unnatural.
