Alembics are quite silent, I don't think you need to record them already compressed. This was a must when the recordings were all analogical and we needed to calm down the peaks (transients) to bring up the main signal. And that was needed just because there were a lot of eletric noise at lower levels setings in a tape machine. In digital realms we have more then 120dB of dynamic headroom and no background noise. So, I don't think it is really necessary to compress a Bass before the DAW if your instrument and pre-amp are quiet enough.
Remember you can change its transients and wave shape using a compressor. Just record that way if you are really shure about the sound you'll be geting. Once you record it that way, you can't step back...
But if your producer really need it, use a good pro compressor, not any pedal. Let it to the gigs, if so. I don't use compressors live anymore since our soundtech will be compressing entire band before send us to the PA. Too many compression in the chain can squash your tone badly.
