You're assuming you're compressing the same sound in both cases. Bad assumption.I understand the above, but it still makes very little sense to me (i.e., running a compressor in an effects loop). Put another way, I'd buy a cold and frosty beer to anyone who could tell the difference between a compressor before or after the preamp in a bass rig on a blind bassis with the gains set equally![]()
If you push a preamp hard, as it's driven harder on the peaks, it may distort some, maybe do something else tonally during those peaks. Let's say you want to preserve "that sound", but then squash it before final amplification so you can maintain a tighter dynamic range at the speakers and still have "that sound".
Trust me, compression is an art form. They can be used in MANY MANY ways. Just ask any studio engineer.
Your example above makes me giggle a bit concerning live bass guitar backline.
