The amp has a set of NOS Sylvania 6CA7s in it and NOS Sylvania 12AX7s as well... NO mods of any kind - bone stock.
This was recorded straight into the amp, everything on 10, variac'd to 90V (bias is 48mA at 90V) slaved into my Fryette PS2 (top switch set to EDGE, bottom switch set to WARM), straight into my recording interface. I used a Celestion IR of a 4x12 w/G12M Greenbacks that had a Royer R121 and an SM57 on it. The only EQ on the guitar is a cut above 20Khz and below 60hz...

BTW, here is the backing track I used, which has absolutely zero of Eddie's guitar on it:

This was recorded with a guitar I built recently, which has a Jalen Frankenstein pickup that is like 14K output:

What do you guys think?
Anyway, to me, it's a great sounding amp and setup...
Here is a little build log as well:
