I trust you and after hearing many a Corey riff, consider you a sensei of tone. That said I'd have to hear two duallies against two full stacks being impractically loud to be a full believer. Maybe I have just trashed me ears to low frequencies but I've always heard it's the highs that are lost first.
Hording regarding 2000s amps should be a term of endearment.
I just fired up the rig and used the settings pictured below. I had a compressor and a UD with gain and volume at 9 o clock and tone at 1:30. It was loud enough to ring the bell in my doorbell(it wasn't anyone at my door), open the doors of my TV stand and shake my BDPG off of said stand. No power amp clipping. I pushed the pre gain to noon and got clipping. Still didn't really hear speaker distress, but if the flanger was on those LEDs would be glowing. I need to put that thing in a blend loop to save the speakers. Note: for the argument of boosting treble or mids for more cut, I am getting A LOT of high end right now due to the response from the faitals. Any more treble and it has a brittle top end and crazy feedback. As for the mids, I had them boosted more before but it was costing low end.
It was VERY loud, but that's without guitars present. It was louder than I'd ever consider in any other band arrangement, but I'm skeptical about its application in Valley. @D.M.N. It still didn't have the low end of the 2000s but may have been louder. I've been toying with much less gain than usual and I've gotten more volume and lows but I feel like less cut through. My dog left the room and came back as I was finishing up. She sat on the chair and looked at me with an expression that can only be personified as "What the **** dude".
I'm not disappointed at all with my choice to go the dually route despite my issues I have been describing. My guitarists create a unique set of hurdles for me as a bassist and I think extreme rig setup is absolutely necessary to compete. The Dually delivers but I think my issues are complicated by my fear of blowing speakers in such an expensive cab.
