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.

Forum discussions:

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

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

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.
