Thanks for all the replies and advice - much appreciated!
However, I'm still somewhat at a loss as to the best solution.
Let me explain further.
Before the switch to KPA, I had two signal chains separated by an A/B box. I was using a Fender Twin for my clean sound, which I could could dirty up with my MXR Dynacomp pedal wich also had a TC Chorus in the chain. For my lead sounds, I used a Cornford MK50II with a tube screamer, micrrovybe in the chain.
Obviously, given that set up, there was no "Rig Volume" parameter. On some some nights/venues the Twin was too loud. On others, The Cornford was too loud and I would adjust them accordingly using the master volume on both amps.
So my question is wether to turn the virtual amp up/down using the soft button "amplifier" parameter or use the physical Rig Volume control on the lower right for best results?
In anyones experience, is one method better than the other?
Kind Regards,
Jeff
