The Vintage filter adds compression. You’re compressing the signal twice. Turn off either the vintage filter, or the compressor pedal.
I’ve been using a Rumble 500 v.3 head into either a Rumble 210 v.3 + a Rumble 112 v.3 cab, just the 210 alone. It is plenty loud enough for the classic rock and blues gigs I’ve played the last couple of years.
I’ve only needed to add the 112 for outdoor gigs.
I leave all three of the Rumble Filters switched to off. I have a compressor on my pedal board. I use a DI pedal (never the Rumble’s built-in DI) to send signal to the pa.
I start with only the compressor switched on and the amp set to “Rumble Flat”. Gain at about 9:00, overdrive off, master at about 10 or 11:00, all three filters always off. Then set my tone control(s)on my bass(es) to my usual preferred setting, adjust the amp’s master as needed for my stage volume. I will usually only make small changes to the amp’s tone controls if any, making larger changes in tone on the bass itself. The only time I change the gain during a show is to roll a tiny bit off whenever I switch to my playing my Stingray since it’s output is touch hotter than my other basses.
If I cannot hear myself, I will usually try turning down my iems (which have everything but bass in them), if that doesn’t work, then I turn up the master on my Rumble.
I’ve never needed to go beyond about 1:00 on the Rumble’s master volume. It’s stupidly loud there.
If I had to go louder than that at any gig smaller than a sports arena, I’d be looking for different musicians to play with. My hearing is more important than any covers gig.
Oh, also check the polarity of your speaker cabs to make certain that one isn’t reversed, and make sure all of your cables are good.
