Which of the three Flint tremolo modes is this best supposed to reproduce ?
how do you create a block like this on the AX8?
lot of info and interesting/pertinent discussion here:
https://forum.fractalaudio.com/thre...molo-settings-as-a-tremolo-block-type.109164/
but for the tl;dr version, @Admin M@ offered up a solution using the flanger block that @yek posted further down in the thread here:

The Harmonic Trem is actually not a pure tremolo effect. It is really a dual-band filtering effect that alternately emphasizes low and high frequencies. The end-result is a soothing pulse that has shades of a mild phaser effect combined with tremolo due to the nature of the frequency bands that are alternated. This circuit required two tubes to create a two-phase differential LFO that controls the gain of the two frequency bands, and then another tube to sum the two bands together. This implementation had a rather short period of availability perhaps due to the somewhat ‘expensive’ implementation. The basic idea is shown below:
One phase of the LFO signal is added directly with the low-band input signal, while the other phase gets added directly to the high-band signal. Essentially, the filtered signal ‘rides’ on top of the LFO signal on its way into the tube summing amplifier. This effectively changes the small-signal operating point of the filtered signal along the tube gain curve. When the LFO signal is at low voltages, the filtered signal will have more gain as the tube operates in its steepest gain region. Conversely, when the LFO is at higher voltages, the tube gain-curve flattens out, and the input signal experiences reduced gain. Since the two bands have opposite phase LFO signals, when one band is experiencing high gain, the other is experiencing low gain. When the two are combined, the opposite phase LFO signals cancel each other out, and the two alternating amplitude-modulated filtered signals comprise the output. This produces the tremolo effect of hearing a loud (bright) signal alternating with a soft (dark) signal.
Also, as a consequence of riding up and down the tube’s gain curve, the filtered signals experience slight changes in harmonic content due to the changing nonlinearities of the gain curve around the signal. This adds further complexity to the trem’s sound.
There's some sauce missing but it's a reasonable facsimile and the approach described in that paper is definitely possible using blocks in the box that are already there. I lost an hour trying to decide what amp+cab pairing I wanted and then f'ing around with a Plex Delay. This box is just too much fun sometimes. Also, my fingers hurt like a SOB from this hiatus.
This is a non-intuitive use of the crossover; It'd be nice to have a link to this thread in the Crossover block guide in the Wiki, perhaps in the tricks section at the bottom of the page.Interesting thread, and very nicely laid out by GM Arts.
At first I thought it wasn't too different from a regular tremolo.
So I used the Tremolo settings from the preset by Sheky, didn't use the Crossovers, increased Depth and decreased Duty for more throbbing and more distinct pulse.
But it isn't the same. The nice thing about the "Flint" settings is that while the throbbing is more apparent, it doesn't affect the higher strings. You can play chords and the throbbing doesn't get in the way at all.
Good job!
Now if this thing could be part of a Trem block as a "type" ...
I've posted a wishlist request:

I don't think I ever did post a preset.Did the preset for this get posted anywhere? The one mentioned above that Matt posted appears to have disappeared when the prior thread disappeared.
A harmonic mode was added to the tremolo block making it mostly moot, I suppose. It's very phaser-y. I like it.Or, did the harmonic tremolo get added to the block as a solution?
Looking at the blurb in the Tremolo/Panner block in the Wiki, it sounds like it's been implemented basically the same way, using crossovers. I agree it's "phaser-y"; I added it to my Tremolo block in my library and have been adding that to my Fender-ish presets and whatever uses tremolo so I can use either bias or harmonic, with bias and harmonic working in their default or with the phase 180º out for stereo.A harmonic mode was added to the tremolo block making it mostly moot, I suppose. It's very phaser-y. I like it.
