I also use a parallel thru, which for me is essential to get the tone I love. I always blend in some pure dry signal from the bass (active, but onboard preamp section usually off). It preserves the punch and transients, no matter what PA guys do to the wet signal at the console (and we know that not once, not twice they do terrible things with it

). In this role my old passive JDI box has got no competition. From the Thru output on the JDI the wet signal begins with a multiband compressor set up at a ratio of 4:1 for lows and mids, just to smooth things out, but 6:1 for highs to bring out some strings' artifacts which I think sound super cool on a fretless.
What's really important to me is that in the TonePrint app I've set ONLY ONE function to the knob, which is the level (volume compensation, without changing the compression parameters). Judging by the comments, people often don't realize that in TonePrint you can assign 3 different functions to the knob, and that they work SIMULTANEOUSLY (so if for example you have level as the first function and threshold as the next one below, by operating the knob on SpectraComp you change level AND threshold at the same time). In many cases it causes serious problems, like people are unable to set up unity gain level (the same signal volume level when the comp is on and off), and some even say it was a deal breaker for them, which is crazy, 'cause it's just a 1-minute fix.
I've found out that my XB Driver plays so much better with a multiband compressor in front of it, it becomes beautifully detailed and nuanced, but at the same time the low end remains tight and powerful. If I record in DAW I run two separate signals, wet and dry, and blend them to taste. Sometimes when I feel like it might help in the mix, I copy the dry signal and process the lows and mids separately with parallel compression. When I go live I prefer to plug in the XBD straight to the power amp input of an amp (if there is one) from the 1/4 out and both XLR outs from SansAmp and JDI to the console. Sometimes it's a 50:50 mix, and sometimes dry signal is better off when it's just barely there, but I fight for it like a lion!
