I had to chance to play for a few minutes today through my Vibrolux Reverb, then later through my 2x10 Deluxe Reverb. It struck me (and my ears told me afterwards) that I play louder through the Deluxe. I think that's because I'm trying to capture the fullness of the Vibrolux. The Deluxe can't do it, though, so I try to make up for it with volume. But it's not the same thing.
