I mentioned in the other thread about having to work a bit harder than I'd expect with the Fractal Rectifiers. I think they sound great, but the top end seems much softer than what I get from using the real amp.
To get things started......
Here is the real amp settings. B/M/T/P all at 5 (parallax making them look slightly different). Gain is at 6.5, master is about 1.8. Not exactly settings I'd use, but I think it sounds reasonable enough.
Recording the amp with it hooked up to a Mesa Oversized Straight/Slant cabinet with 2002 V30's. Tapping the amp DI signal with an Ampete switcher.
Applying an IR on the real amp DI gives this:
So when comparing with FM-3, I decided to route directly into the main input. My reamp box is calibrated for my I/O and its going through the same reamp path as the real amp did. I used Recto1 Red and Recto2 Red Modern. I started with both at the same settings, lowered the bias a bit, turned the preamp LPF all the way up, and then tried not to tweak too far from the real settings. I used the 4x12 Recto Large impedance curve (which matches the response of my cabinet closest IIRC).
That yielded this for Recto1 Red:
and this for Recto2 Red Modern:
and just as a kind of "control", here is Helix's Rectifier. I started with settings all matching the amp and just fine tuned a little:
which makes:
The Helix definitely has some signs of its trademark fizz on the top end. I believe both the Helix model, and also Fractal's Recto2 Red Modern are from a 3 channel rectifier. In my experience, its quite possible to match the tone of the real amps very close if you are careful with settings.
Even with the presence on 10 and the treble dial turned up high, the Fractal Rectifier isn't giving me the same amount of top end as the real deal. I don't think its simply a case of pot tolerances, circuit variations, or different impedance curves causing such a wild difference. I'm not saying it isn't user error either, but I'd love to determine where the difference is.
Higher quality audio can be listened to and downloaded here. I also included the amp DI signal, and guitar DI (11.4dBu input headroom) which can be downloaded if anyone wants to try matching the Fractal Rectifiers to the real amp tone.
There is also a NAM model made of the real amp with this chain: https://www.dropbox.com/scl/fi/xonm...Test.nam?rlkey=3yseofmj1s6z65d3fsiqbpige&dl=0
Would be AWESOME if we're able to get these Rectifier models to match closer.

I'm not expecting the models to match the amp though, they never do in my experience.
