** You want the signal to be as loud as possible at the end of the signal chain (without clipping as mentioned above), before it is converted from digital to analog, in order to get the best signal-to-noise ratio. But if the patch has a Parametric EQ behind the amp, this means you have to keep the amp volume knob conservative to avoid clipping it. I do one of two things to work around this issue. For a mono single-amp tone, I put all my post-amp effects after the amp but before the Mixer. I use the Mixer to boost the signal level and pan to center for that channel, and I mute the other one. If I want a stereo tone or dual amp tone where that option isn't available, I try to put a Studio or Mid-Focus EQ as the last effect in my chain and boost with the Gain parameter (this has no effect on how much EQ'ing is happening). I get as close to clipping as possible, and I test it with a few different guitars and style of play to make sure no aggressive playing or certain notes don't push it into clipping.
** You want the Master knob to be set as high as possible to achieve the best signal-to-noise ratio, but you have to balance this against clipping an external device. Follow the same guidelines as above - you definitely want to be below clipping but try to get it as high as possible.
* Certain full amp models model crossover distortion in their power section such as the Blackface Dbl, AC15, and AC30 models - it sounds similar to digital clipping. I find the best way to dial this back without altering tone is to use the DEP (deep editing parameters). Turn Master down and Bias X up. Other methods to reduce the clipping is to reduce the amp Drive parameter, change Input 2 to Variax (or Mic or some other null input), or put a Studio EQ in front the amp model and turn down the Gain parameter.
