Sure, I'll someimes use something like an L1/2 or the such for parr comp on the bass. I usually make it so the bass never changes in level. It works great sometimes, other times it sounds really bad.
Splitting the bass into two sounds works well. One for bottom, one for mids/growl and keep both elements focused. Daking for bottom (i'm sure a neve comp would be great too), 1176, distressor or 160 for mids. I've never had much luck with opto comps on bass but I don't have an LA2A.
The original bass compressed with less effect as possible,
usualy with an LA2A or the Atomic Squeeze Box, and than a mult with
either a Distressor /w brit mode or an 1176 squeezed so that you get
an constant, smooth and long sustain, mixed back underneath.
That's my usual starting point, gear could vary also, depending of the recording.
