ACOUSTIC IR’s (not included, but you can use them with FM3)

Acoustic Impulse Responses can make a massive difference in your direct acoustic tone. The FM3 does not have an IR player block, but you can load IR’s into the ‘Cab’ block. We’ve left an open block after the compressor in the signal chain where you can insert the cab block.

To use an acoustic IR with this preset, insert the cab block after the compressor and then load an acoustic IR into one of the cab slots. With acoustic IR’s, you may need to turn the output up to +9-12dB.

The reason we did not include the cab block in the preset by default is because it will mute the output of the preset unless there is a cab or IR loaded, even if it is bypassed.

EQ: PARAMETRIC EQ 1: This is meant to be an always-on EQ. It does basic tone shaping for acoustic guitar.

EQ: GRAPHIC EQ’s: These EQ block can make your overall sound brighter or darker. If your guitar sounds too dull or dark, engage the ‘Brighter’ EQ. If your tone is too bright or thin, engage the ‘Darker’ EQ.

EQ: PARAMETRIC EQ 2 (NOTCH FILTERS): This parametric EQ block on the bottom row is meant to serve as notch filters to eliminate feedback. These four EQ’s notch out frequencies on the lower four strings on acoustic. If you are experiencing feedback on the low E string, engage channel A. If you are experiencing feedback on the A string, engage channel B. If you are experiencing feedback on the D string, engage channel C. If you are experiencing feedback on the G string, engage channel D.


This preset is in stereo. If you are running mono, you’ll want to set up FM3 to sum the preset to mono.

The easiest way to make this adjustment is in the ‘Setup’ menu:

  • Choose ‘Setup’, and select ‘I/O’
  • In OUTPUT 1 CONFIGURATION (choose the physical output you are using), change the ‘Mode’. Select ‘STEREO’ if you are running in stereo. Select ‘’SUM L+R’ if you are running mono. This will convert your output to mono and sum the stereo image. This will also cause all your presets to output in mono, as it is a global setting.


FC-6 // OMG9 Custom Layout

This preset is optimized for the OMG9 custom layout for the Fractal FC-6 controller. The OMG9 Layout is available here from Fractal:

The ‘Effects’ layout has been modified with custom overrides (see below) so you will see the effects that are relevant to this preset.

If you’d like to change any of these assignments (either the Per-Preset Assignments or the Overrides), you can do so in the ‘CONTROLLERS’ menu on the Axe FX III. Press ‘CONTROLLERS’ from the Home screen, then select ‘Per-Preset FC Settings’ and make changes.

If you would like to go back to your default settings for Layouts 7 and 8, you can reset the Overrides from the ‘Overrides’ menu in the ‘Per-Preset-FC Settings’ section.



All guitars are different, so you may want to make changes to suite your playing style and guitar. To adjust the preset for your guitars, the primary controls to adjust would be:

  • EQ settings (PARAMETRIC EQ1). The parametric EQ can do most of the work necessary to shape the overall tone of the preset. If your guitar sounds to bright/thin, remove highs and add low end. If it is too boomy or dark, remove low end and add highs. You can also engage the ‘Darker/Brighter’ Graphic EQ’s.
  • Volume/Output level. Acoustic guitars can vary quite a bit regarding the output level of the pickup systems installed in them. Most guitars have a volume control on the preamp. You want the output of the guitar to engage the compressor but not by a large amount. Axe-FX III will show you the level of gain reduction on the compressor. You want to see between 3 and 5db of gain reduction. If you are seeing more than that, try to lower the level coming from the guitar. You can also adjust the threshold control on the compressor. From there, you can adjust the overall volume of the preset by using the output level of the compressor block, or the output level of the ‘Out’ block.
