NOTE: This firmware requires installation of Dyna-Cabs version 1.09 if upgrading from firmware prior to 30.00. Refer to the Dyna-Cab Installation Guide for details. Be sure to install the firmware before installing the Dyna-Cabs. The file is here:

Axe-Fx III Firmware Release Notes​


31.01

Added “Deluxe 6G3” amp model based on the bright channel of a 6G3 “Brownface” Deluxe.

Added “Citrus Juicer” Compressor model based on a Dan Armstrong Orange Squeezer. Unlike the Orange Squeezer the model allows you to adjust the compression ratio and threshold independently and also features Emphasis, Drive and Tone controls. The ratio and threshold of the actual pedal vary with the particular JFET used and the internal bias trim. Set the Threshold to -26.0 dB and Compression to 8.0 as a starting point and adjust to taste.

Added “Half-Wave” Detector Type to Compressor block. This is similar to the Peak type except the rectifier is half-wave as opposed to full-wave. This alters the attack and release ballistics and can add a bit more grit to the sound.

Added warning if system clock frequency is incorrect (e.g. when using AES/SPDIF as the clock source and the clock is at 44.1 kHz instead of 48 kHz).

Improved Amp block preamp modeling (again). This yields more accurate behavior when the amp input is pushed (e.g., when using an internal or external overdrive/boost).

Improved Amp block phase inverter modeling.

Went through every model with a fine-toothed comb and adjusted power amp and phase inverter parameters as needed to reflect new modeling.

Improved dwell algorithm for spring types in Reverb block.

Fixed wrong output transformer impedance ratio in Deluxe Tweed models (only slightly off).

Fixed wrong bias point in Band-Commander model.

Fixed instability in Pi Fuzz model for certain values of Sustain.

Fixed wrong time constant in Herbie models (probably not audible).

Various other fixes and improvements.

Hello ,

I use the AC-20 EF86 Treble a lot.

With this firmware, the sound is very thin, less powerful, no bass, less drive.

Until now, I used it with the FW 31.00 and it was very good.

I also have an FM9 (FW 10.00) with my settings.
I was able to compare the 2, the difference is obvious.

I don't know if it's normal.
Do I have to rework my sound drastically?

Thank you again to the whole team for all the work you do!!

Changes in tone are normal with firmware updates. Presets usually need to be tweaked slightly to sound the same as before. If the change you are experiencing is big, make sure there isn't another variable aside from the firmware affecting your tone. And remember that firmware updates are optional.

Is your cab block poiting to the right ir? Caught me out after one of the recent updates

Yes, it's not stupid!
I just checked, no it's ok.

I reinstalled the firmware in case of doubt, but the same.

I compared with my FM9, and the only difference I find is in the "preamp" section.
Tube hardness at 3.75.
It's at 7.4 on my FM9.

Indeed, I get closer to my sound by modifying it to the same value as my FM9, even if a little different but close.

Before I'm asked, I don't grind these kinds of settings, I only change the standard settings.

So, I wonder if it's a wish of this firmware or not ? @FractalAudio ?

I agree with that, having the habit because it's been many years since I switched to the fractal world.
But this change is radical, hence my question.

No other variables, as specified above, I just notice that the value of "tube hardness" is very different, and therefore the sound changes radically.

After that it doesn't matter, if that's the desire of this firmware, I'll update myself in my settings

Yes, that's a mistake in the new firmware. Set preamp hardness to 7.4. This will be fixed in the next release.

Thank you for your quick response!

I have indeed noted that the hardness tube values are very different on the amps I use compared to the previous FW, but, apart from EC-20, the changes are not audible.

Band commander: 8.4 to 2.6

EC-20 EF86: 7.4 to 3.75

Plexi 100w 1970: 7.3 to 2.2

Thanks again

Aside from the AC-20 EF86 those values are correct.
