What is the Formant block

The Formant filter simulates human vowel sounds.

There is more information at Wikipedia's Formant page and in the Owner's and Blocks Manuals.

Position of the Formant block on the grid

For best results, put the block between the Amp and Cab blocks.

Factory presets

The Formant block is showcased in a few factory presets. See the download pages for each product's specific presets:

• Axe-FX III
• FM9
• FM3

NOTE: The Axe-FX III can load all presets for the FM9 and FM3, but the FM3 won't be able to load all presets for the FM9 and Axe-FX III. Similarly, the FM9 can not load all presets for the Axe-FX III but can load all FM3 presets. This is because of hardware limitations in the smaller units. In all cases, attempts have been made to ensure the sound of the preset has been preserved as much as possible. Review Effects in the FM3, FM9 and Axe-FX III comparison for more information.

Tips and tricks

Simulate a talkbox

The Formant effect lets you simulate a talkbox and, if you really really must, play Livin' on a Prayer.

Attach a controller to the Control parameter in the Formant block, either an internal controller such as an LFO, or a pedal.

The Forum discussion has more information.

A real talkbox doesn't use a speaker, so experiment with leaving out a Cab block in the preset.

Do you want tips for integrating your real talkbox in your Axe-Fx or AX8 rig? Search the forum for "banshee" or "talkbox".

Also see "Talk box" at Wikipedia for more information.

Emphasize frequencies

The Formant can be used to emphasize frequencies, for example when creating a Seek Wah effect. Put the Formant after the Wah block.

Make other sounds more vocal

Add the Formant to make other sounds more like human vocals.

Prevent clipping

Because of the resonant frequencies of the Formant filter, it's easy to make the digital signal clip. Keep sufficient headroom.
