You'd think so amigo. But I tried it next to the A/B and liked the Studio Feedback one better (more accurate). I can get the Cali 1176 thing going with two comps in series a la Little Feat. I also really like having the compression threshold grid while I play happening, so I can see what is happening visually (so it's not a total guess), and as I recall that one doesn't have that... I don't think Cliff was building in unique compressor tonal "color" into any of these, but perhaps I'm wrong...I am surprised you did not go for the JFET for the 1176 sound.
I sometimes stack two JFETs for that huge stacked 1176 slide (Cali SlideRig) sound
