Also, (this might have been mentioned but I didn't read the whole thread)
On the unit itself, once you pull up a rig with the amp that you want, you can press and hold the cabinet button and use the browse knob to scroll through all the cabinets in your rig library.
Example:
You pull up a Princeton Rig that you like but you want to audition different cabinets.. Press and hold the cabinet button till it flashes, use the browse knob and start scrolling until you find say a 4x10 super reverb cabinet (idk if that's a real thing but it's what my brain went to). This is my favorite way to mix and match amps and cabinets! (you can also do the same process with Amplifiers by pressing and holding the amp button)
