Jeff, am I hearing a little "power-amp hair" on that tone, or is it just me?
If so, and if you're "picky" to that end, you might find you have to dig around a little in order to recreate that bite.
I'm not really sure, MM. I don't know that my ears can detect power amp vs. preamp tonal additions once you through in different cabs or mics or mic angles, room ambience, etc...
Can you describe what you are hearing that would lend itself to being more power vs. pre? I believe he just used a Laney 2x12 with his Laney GH100L and an SM57 for this recording. Minus any "studio magic", that is.
