It's expensive, but I understand a lot of Nashville session guys are using the Wampler Ego Compressor. I've also heard good things about CMATMOD's compressor models (lower price points too, but I don't think they have a blend control like the Ego). There are sound clips and/or vids on their websites (wamplerpedals.com and cmatmods.com). I don't have, and haven't played, any of these, but I do own one pedal each from these companies, and the ones I have are very good quality (Wampler Leviathan fuzz, and CMATMODS Deeelay). I don't know if this helps, but they might be worth checking into.
