I know it sounds contrary to logic but, this is how it works, Doc.
You want to reduce the headroom to have cleans with body enough earlier and, therefore, play at lower volumes.
With low gain tubes, you will get no body in your cleans until you reach more or less the break up boundary and, this will force you to play louder.
So, with high gain tubes (both preamp and output?) I can get to that "pushed" tone at a lower volume because the tubes are breaking up sooner? With high gain tubes I am essentially reducing the clean output of my amp? So, for example, instead of getting to that nice thick tone at, say, 70% volume, with the high gain tubes I'm hitting that spot at 40% volume?

That's the idea.
Weird, isn't it?
But I don't think you can reduce it so much. Max. 20% of reduction.
As said at the very beginning, your best bet is a speaker change but, tubes will help, also.
Re: Need amp guru - help me reduce Egnater Rebel 30 power
One more idea. If you like your current speaker sound, you can always try same speaker with higher impedance. If you are going from 8 Ohm to 16 Ohmn, you are somewhat dividing by 2 the power of your amp.
Which is your current speaker?.
Maybe a Jensen P12Q can do the trick?.
It's rated to 40 W RMS, 80W peak.
Sensitivity: 95 dB.
Maybe, you can take the 16 Ohm version, to damp your amp's power.
Webber should have an equivalent, theoretically better sounding. Not sure if cheaper.
Re: Need amp guru - help me reduce Egnater Rebel 30 power
I am currently using a 2x12 cab with an Emi Swamp Thang 8 ohm and a Celestion G12k 8 ohm wired series (16 ohms). I don't mind using one of my 1x12 cabs if the speaker is right and gets me the tone I want.
Are you saying that if I use my 8ohm speaker and set my amp to 16 ohms I will reduce the power of my amp? Or are you saying that I should use a 16 ohm speaker (instead of 8 ohms)? And should I match my amp output to my speaker impedence (16 ohms amp setting to 16 ohms speaker imp.)?
Re: Need amp guru - help me reduce Egnater Rebel 30 power
I mean your amp at 8 Ohm and the cab at 16 Ohm. That happens if, by example, you have an attenuator paired with your amp output (8 Ohm) but, you hung a 16 Ohm cab. You are adding load.
Maybe, it's a crazy idea but, those are the things that I would test.
One more suggestion, Doc. Do you have some clean booster around?
I am doing the trick feeding the signal with an EP Booster at the very beginning of my chain, what leaves me to warm the pre-amp to get an earlier break up, while lowering the volume.
