Unplug everything ,check all your cables then just hook up straight in with nothing but the guitar, head and cabinet. Nothing in the effects loop. Nothing in between the guitar and the amp. If it's not tubes or a bad cable or connection ,then I'm out of easy ideas for what it could be. That would only leave some other internal issue and might need to be looked at by an amp tech.

This is embarrassing but I had a similar issue for a couple days. Low gain, just lost the tone. I wondered what was going on with amp. Ended up my volume pedal was slightly cocked and lowering the input signal.

Seems your issue is different, though, since you have a V:25 to compare it to (assuming identical signal paths). Maybe the amp itself has an issue. It may be time to contact Mesa.

When I first got the JP2C I was thinking the same thing. Ultimately it came down to EQ and volume. At low volume I need shred mode to get a good tone. Also at low volume I find myself turning the EQ knobs more, particularly treble, presence, and the low/high EQ sliders.

I just had an interesting revelation... It appears that the gain knob on channel 1 affects the gain on channel 2 and 3. Do any of you know if this is intended?

No, the gain on channel 1 should not affect the other two channels.

I've already sent the amp back in for repair, although it's a shame I didn't realize that the amp had this issue when I initially purchased... Oh well :x When I get the amp back I'll update this thread with new sound clips using the same settings just for others who may be interested in the sound.
