I get my amp shortly and already have a 300.

I'm really looking forward to linking them and really trying to get the best out of the, both.

Is there anything I should know to get the best result??  Ie. turn off amp models or cab sims or output modes etc etc.

I tried one out in a shop together a while ago and wasn't impressed - but I admit I didn't know what I was doing and didn't put enough time in.

Cheers.
