not a dumb question at all. I'm not a compressor expert either, and talking about tone is (as Frank Zappa or Martin Mull once said) like dancing about architecture. But, I have used a few pedals (BBE Opto and EBS MultiComp) and a few amps with one knob type comps on them over the years and had some experience with comps in recording work since the 70's.
For one thing the Cali76 has a few more controls than the others I have used so it's more tweakable. As I mentioned above, using the parallel (NYC, sidechain) setting allows you to get quite a bit of compression but keep your signal mostly (more?) unaffected by pushing up the Dry control (so more of your bass signal). The result, to my ear is all the good stuff about compression .. dynamic control and even-ness, and punch/heft to individual notes, with little of the usual comp downside which for me is usually experienced as choking the notes.
Now I also find the Cali76 to be pretty "musical" sounding .. to my ears it's not super transparent at all .. it adds an openness and depth, as well as some sweetness in the high end for definition ... again to my ears.
So how I experience it is the Cali punches up my signal, evens out my dynamics a bit, then that goes to the Noble for what it does .. tube warmth and whatever superlatives you want to use about the Noble. At the end of all that I run an HPF to cut the mud below about 40hz and keep all the other tone goodness.
very happy with this signal chain for the past 2 years.
now back to your normal Noble DI programming
