cue funny compressor meme....
since you use the ax3 , use the Type Pedal Compressor 1
Quote from fractal forum admin...
The PEDAL 1 type in the AX8 is comparable to the CS1/2/3.
The COMPression knob is equivalent to the SUSTAIN knob on the Boss pedal.
Release is not sustain. Leave it at the default setting.
When using this effect, I like to increase level before the compressor. One way to do this is to increase the output level of the noise gate on the input block.
As for settings reference from Ed's picture and copy onto the fractal, but I would suggest just using your ears and feel out what's best for you
you might not necessarily need the same compressor settings to sound like him because it's highly dependent on your playing style how much it compresses..... also got to account for the pickup type/output
