Any recommendations on what effect to use to get that slicing sound? Right now I'm experimenting with some flanger and tremolo. Close but...
Here's an Axe II preset you could convert with FracTool.
The pan/trem block doesn't provide enough control over the LFO shape for this, so a volume block with LFO modifier is used. Envelope runs the LFO when you play a note for proper sync. There's also a ~32nd note slapback delay and a gate last, sidechained to input.
Whew - I'd be interested in your preset(s) for that song !! (which Amp/Cab for the main riff?)
Do you have a Keyboard player in the band ? If yes I'd maybe consider to leave the intro to him/her. And if not, there's also some Arpeggiated synth drone sound going in in the Refrain, which the AX8 could possibly also recreate - check e.g. Andrea Puxeddu or @simeon 's stuff for inspiration/how-to ... ;-)
