Multiple functions on the expression pedal

[Doylej]

Hi, big fan of the old guitar port and pod xt but have spent a few years in the (bewildering but brilliant, and noisy) wilderness of boutique analog pedals, I'm looking for a bit more flexibility and ease of use. I was thinking of grabbing a firehawk. I have question about the expression pedal. Can you assign multiple parameters to it at once? Eg if I had a 2 amp setting could I use it to fade one in and the other out like a crossfade? Also can you assign the mix level of a distortion to it? I'm thinking of it as a way around the much maligned lag when changing presets, that and swells into massive choruses.

There is no 2 amp setting, if you want that then Helix is the way to go, not sure if HD500X has dual amps or not.

 

As far as controlling gain with the pedal, you can do that.  You can place the volume pedal in front of your overdrive pedal or amp model and increase/decrease "gain" that way, similarly to how you would with a volume pedal right after a guitar.  That's what I do. I set the minimum pedal position to 10% so it's a no-brainer and start from there to build my sound.  I get a great clean and transition into dirty that way.  I use a Screamer HD as a boost to get even more dirt and a great lead tone.
