add phase-reversal to the gain block

[guitarsenall]

Please add a phase-reversal parameter to the gain block. 

Flipping the phase (e.g., polarity) is a CRITICAL and effective strategy for fighting low-frequency feedback for acoustic guitars. There is no simple way to do this within the current Helix Floor.  If I don't have the switch on my pickup, I am up the creek. 

The gain block is the simplest place to put it: an option for "negative gain".

To invert the phase set up a Stereo Width block  [Volume/Pan (Stereo)] like this:  

Width Center, LR Swap Off, Balance R100, Level 0.0dB, RPolarity Invert

 

...and use a (any) mono block after it.

 

 

Why do I need a mono block after it you ask? 

With the above mentioned setting the inverted signal leaves the block on the right channel only (left muted). A mono block after it automatically sums L (no signal) and R (flipped phase signal).

Genius. By "Width Center" do you mean set the width to 50%? or zero?
Thanks.

"Center" is 0%.

 

Tip: Save the block as favorite for easy access and name it "FlipFlopper" or something even funnier. ;)

Have fun.
