White Light of Death,
As I understand it, the "extra mid range thump" is the thing that leads to the perceived difference. Indeed, I think the Wiki has a section that also points to this as a way to get to the traditional cab feeling with a pointer on how to EQ it in.
Therefore - EQ it in if required? I went for CLRs and have no complaints either in my studio or out of it.
Alternatively, EQ out some of the FRFR lows and highs, again in the Wiki :
FRFR and amp/cab-in-the-room
Use the parameters below to get the sound of FRFR amplification closer to the familiar "amp/cab in the room" sound.
Cab block:
- Room Level
- Floor Reflection
- select a "far-field" IR. The stock ones have "JM" in their name. Or: select a stock cab which has been captured with a neutral mic, such as the Red Wirez ones, and set Proximity to its lowest value for simulate far-field coloring
- create the so-called "HAAS" effect by using two IRs in stereo, with a very short delay in the Cab block on one of them
- use De-Phase / Smoothing
- use Low Cut and High Cut to shave off excessive low and high frequencies and mimic the frequency range of a traditional guitar speaker
