[Edit Apr. 22th, 2024] Updated preset for FW8 (Cygnus X-3) is available on Post #11. The presets attached to this post is obsolete so deleted. Demo video is taken down as that no longer demonstrates the current version of this preset.
Attached is my presets to simulate Brian May's "Wall of AC30" touring rigs (in 2000's and after), re-tweaked for FM3 w/ firmware ver. 7.00 or after.
(Originally for AXE-FX III, available at: https://forum.fractalaudio.com/thre...available-for-fw22.189154/page-2#post-2431557)
I made 3 separate presets to meet different use cases. Here are the brief introduction of each preset:
“Wall of 9 AC30s FM3 |km 202257”
I'd like to acknowledge Yonderbosk as the manufacturer of the treble booster I played with my preset “Doctor's Fav AC30” on this demo. If you liked my tone there, check out "BC149 ‘Orange Label’ Treble Booster" at http://yonderbosk.com
Keep in mind that Chorus is bit more "Chorus-y" on the attached presets due to the updates mentioned in the additional notes below.
This is the FM3-specific notes. The resulting tone is different from what I intended, due to:

“Wall of 9 AC30s FM3 |km 202257”
- This is my take of Brian’s rig for the gig, including the chorus, pitch shifters, and Brighton Rock delay.
- You can choose either chorus, pitch shifters, and Brighton Rock delay by changing the Scenes.
- This comes with the simulation of a treble booster (the Drive block) so you can directly connect your Red Special or any guitar into Input 1.
- If you want to use your real treble booster, connect the booster to Input 2 and apply the following tweaks to the preset:
- engage Input 2 block in all the Scenes,
- turn off Input1 and Drive block, and
- change the "Tonestack Type" of the Amp block to "Default"
- If you want to use your real treble booster, connect the booster to Input 2 and apply the following tweaks to the preset:
- This is what Scene 6 "Eventide in Get Down Make Love" on the original preset is separated as a dedicated preset to meet "1 pitch per preset" limitation on FM3.
- Specifications on Inputs are the same as “Wall of 9 AC30s FM3”.
- This is intended for studio recording quality tone. Chorus, pitch shifters, Brighton Rock delay, FX Delay, and Reverb are not available.
- You’ve got 3 scenes with different cab/mic placement. On Scene 1-4, simulation of a treble booster (the Drive block) is engaged, while on Scene 5-8 it’s bypassed so that you can connect a real treble booster to Input 2. (Scene 2 and 6 are intentionally left blank)
- For all the scenes, Cab block comes with a combination of dynamic mic IRs and condenser mic IRs. Dyna-Cab is used on Scene 4 and 8.

Keep in mind that Chorus is bit more "Chorus-y" on the attached presets due to the updates mentioned in the additional notes below.
This is the FM3-specific notes. The resulting tone is different from what I intended, due to:
- Phase cancellation in Scene 1 "Chorus".
As the core tone is completely the same in both dry and wet signal, they cancel out each other and the preset sounds thinner.
This is why I had to use 2 amps/cabs on original presets. By creating the offset between dry and wet signal, they do cancel out each other but to less extent. - Input Impedance not adjustable on FM3.
Generally, treble boosters have input impedance around 100kohms. To replicate the interaction of devices with such low input impedance and PUs, I programmed my preset to set the input impedance to 70kohms on AXE-FX III and FM9, whereas FM3 is fixed at 1Mohms.
- playing with a real treble booster connected to Input 2, or
- before Input 1, connecting an impedance adjustment device (such as Radial Dragster: https://www.radialeng.com/product/dragster) to bring down the impedance loaded onto PUs anywhere below 100kohms
- Drive block’s got a different setting for each channel and are set to the channel that matches best to each of the scenes. Here’s what each channel has got:
- Channel A: matched to a treble booster by Fryer guitars by ear. Similar to Brian May’s treble boosters in late 90s-2000s.
- Channel B: matched to a treble booster by Pete Cornish by ear. Similar to what Brian used in late 70’s to early 80’s.
- Channel C: Almost the same as the default of the “treble booster” model but with clip type changed to “Germanium”. Intended to simulate what Brian used in early 70’s
- Channel D: The default setting of the “treble booster” model.
- After experiments, I recommend treble boosters be connected to Input 2, not 1.
- However low I turn down the input level or A/D sensitivity of Input 1, it never stops clipping when a treble booster is connected. It is not the case with Input 2.
- For the presets/Scenes intended for the use with a real treble booster, the gain of Amp block is adjusted to improve S/N ratio.
While with these presets/Scenes I feel the AXE-FX is behaving very close to the real AC30, you may find the gain is lacking especially in the solo. Adjust the gain in that case or I recommend using the presets/scenes with Drive block engaged.- Actually I prefer using the simulated treble boosters as it can achieve higher gain and still tolerable S/N ratio.
- I didn’t include the foot controller configuration. Please do the configuration yourself If necessary. If you are gigging with my presets, I guess you’d want to assign switches to change the Scenes and control other FXs.
- Chorus block is updated from the AXE-FX III version to match with Brian's own chorus settings.
- A new information on Brian's settings of his FX effects (TC Electronic G-Major 2 BTW) becomes available by Doug Short, who asked Brian's guitar tech Nigel Knight to build the same rack unit as Brian's, including the same setting of chorus and other FXs as Brian's. The parameter is available on Doug Short's website (https://dsgb.net/gear/brian-may-live-rig/)
- I applied the same settings to the Chorus block of my presets, except for "LFO Phase" tweaked a bit to obtain a better stereo effect and "Delay Time" to replicate the latency by TC G-Major's A/D & D/A conversion.
