Are you saying, that you have no sound at all, when you select the "Stage Basic" preset? If you have to do anything else to get sound, then you have an issue, that i for one don't have.
And apparantly you have a different behavior when you use the "Default" preset/ New Preset. That's very strange.
Do you get sound when you simply select the "Stage Amp" factory preset? Just select it and play, and nothing more. To me it sound strange, if you have to activate the Chorus or any other pedal to get sound at all.
When you have the amp on, and you say all volume related adjustments is at maximum, then are you saying, that you also have the Bass, Mid, and Treble parameters at maximum?
If the EQ parameters is at zero, then you get very weak volume, and that's normal. So what are your EQ settings?
Activating the amps "On Axis" will introduce a little noise.
Which version are your application? Are you updated?
Have you tried to uninstall and reinstall the application?
I only know about the delay still having clicking issues with the feedback parameters like reported in another thread. Other things have been fixed i think.
