Extend the signal chain on the grid

You can use Feedback Send/Return to connect the signal chain on the grid from one row to another. The manualexplains how this works.

Combine with FX Loop to send Input 2 to Output 2 on the Axe-Fx II

Feedback Send and Return can be used to enhance the effects loop on the Axe-Fx II. By itself FX Loop enables:

  • Letting a signal from Input 2 to enter the grid
  • Sending a signal through Output 2.

By placing FX Loop inbetween Feedback Return and Feedback Send, you can accomplish both: send input from Input 2 to Output 2.

Configuring Send/Return

Axe-Fx II – both blocks have parameters which need configuring. In most cases you'll want Send to feed the Return block only, not to pass signal to the next block. So Send Level (signal to Return) has to be at 100% and Output Level (signal to next grid block) stays at zero. In this case the Return block's Mix parameter (signal from Send) should be 100% and Return Level (signal to next grid block) is 0 dB.

Axe-Fx III and FM3 – Feedback Send does not have any parameters to set. The signal to Feedback Return can be controlled with Mix in the Feedback Return block (default: 0). And if the signal is passed to the next block and needs adjustment, there are other tools to accomplish that, such as a Volume block.

"The reason the default level for the Return Block is 0 is probably so that when you insert it, you don't need to fear screaming feedback. The way it is, you can turn it up to make sure you haven't created a bad feedback loop. source

Protection against feedback runaway

"The feedback return will clip at extremely high input levels. This is a protection mechanism to prevent against "runaway" if someone creates a feedback loop. The feedback return clips at a level of 38 dBu. This is nearly 10 times the maximum output level of the unit. If this protection were not there a feedback loop could be created that would result in digital overflow and cause a reboot." source
