Yea, it appears to be the case. Both Fat & Tite Clean are about the same vol but Crunch takes a major jump, I believe switching to that voicing adds another preamp tube in the chain. You may also notice with Ch2 that the Tite Gain and Fluid Drive see increased vol over Crunch on that chan. The vol difference between Ch 1 and Ch2 is also a major one if either Fat & Tite Clean is used.
For live work a few approaches to better balance... using a vol pedal in the loop, clean boosting Ch1 or use Crunch with the gain way down.
AFA pristine clean settings IMHO alot depends on how hard the front end is hit. It's a real dynamic amp that respond well to pick attack and cleans up well with vol rolldown. Also alot depends on the speaker choice and pickups.
