That’s not the case on my Combustion, there’s a noticeable volume bump that happens when you engage active mode on that bass.
Just FYI I would say that's not normal for a combustion either, I think you said it had low output as well. I'd get both of these basses looked at cos neither of your basses match my experice.
Every Combustion I've had there was no difference in output switching form active to passive and if I had the EQ set flat I would never know which mode I was in until I started turning knobs.
I had a Glock in my Super J and if anything it was too bassy.
