The clean boost is if you want more overdrive, not less.
You don't have a problem. Keep the pad off if you want some subtle tube overdrive and keep the pad engaged if you want no overdrive. Then turn the gain knob up until you get a harsher clipping, then turn it down a bit and leave it there. Then use the master volume for your volume like usual.

You need to adjust the compression. Watch one of Dino's videos on Youtube about properly setting Gain.
I have to set my compression on one bass as high as noon before I can dime the gain. I promise you if you dime your gain and the volume, this amp is way louder than your PF500.
He only needs compression if he wants compression. Yeah, a compressed signal will allow a higher RMS without clipping. But the 7-PRO will still get very loud without compression.
Yeah, but if I control my input clipping with compression properly, I can really dime the gain and this amp will blow the doors off all the houses in my "neighborhood" (I live in the country).
This is true. And the compression does have a cool sound, and I like the single-knob simplicity. I've been using an overdrive pedal more often lately, which seems to be compressing things enough for now.
I have one pedal that has a nice compressor, but honestly, I prefer the compression on the amp head to any other compressor I've tried so far (only 3, but still). It does it's job very well without affecting the sound/tone in my experience.
The post from @Treblefree reminded me that the compressor is also a way to control input gain (as opposed to preamp gain). Today I plugged my passive jazz straight in, pad off, and had a little too much gain from the input, so I set the compressor to about 8:00 which cut the fizz but left some subtle drive.
So if you do this, you have to set the preamp gain by ear because the clipping light is already lighting up from the input clipping. So just turn the gain knob up until you hear the preamp clipping, then back it down a bit.
There is a somewhat narrow band of usable drive in the 7-PRO due to the single input tube, but it sounds great if you can dial it in.
So there is one more way to get overdrive form the 7 Pro that I had basically forgotten about. If you crank the compressor high enough with a hot enough signal at the input, it will begin overdriving.
According to the 7 Pro block diagram, the "tube preamp" is situated both before and after the compressor. I suspect the compressor is not only compressing the signal as you crank it, but increasing its output to the 2nd portion of the tube preamp and overdriving it.
This may be the intended way to overdrive this amp as it sounded good in my brief tests last night. With my Jazz I was able to get a good crunch going with the compressor all the way up soloing the neck pickup. With both pickups on, it was quieter enough to need my clean boost pedal to dial in the same amount of drive. A headphone test revealed a very warm/dark overdrive that would play well through the direct out.
I'm going to mess with this more at higher volume today and see how it goes.

So my daytime tests today pretty much held up. I guess I pluck a lot harder in the day as I didn't need the clean boost with both Jazz pickups on, and could get a nice drive with the compression at 11:00. I think I'm ready to ditch the overdrive pedal with the band and plug straight into the 7 PRO.
Guys, have you ever tried to power two 810 with one single SVT 7? I'm aware this. would run the amp at 2 ohms, but. the guy from Motionless in WHite seems to do this without any issues. At 14:20:
Yes it does, but this guy seems to use it that way without any problem. And Ampeg says it's not recommended as it " could overwork" the amp: [Invalid or Expired Link Removed]
It looks like it's actually possible and works fine, but don't complain if something goes wrong....
No offense to the guy, but he also said it was 100w when it's 1000w, so I don't know if I'd follow his example
Haha! I did notice that tooNo offense to the guy, but he also said it was 100w when it's 1000w, so I don't know if I'd follow his example
I even put a comment about that.BUt.... It looks like the amp can sustain 2 ohms load. I'm tempted to try. And I swear, I won't moan and cry if it fails
The amp was designed for a 4 ohm load - running it less than 4 ohms stresses components and reduces any sort of safety factor the engineers designed into the amp to zero.
There's a real risk of failure, - failure could include outputs shorting to rail voltage - which might blow speakers, and failure could also include electrical fire - so you want to risk the safety of your fellow band members, venue and venue staff, etc etc etc.
If you want to drive 2 x 810s, THEN USE TWO AMPLIFIERS ( Glenn Fricker voice ) - and we wonder why bass players have a reputation of being dumbasses.

I'm aware of all this. However I don't think bass players have a reputation of dubasses.
This guy seems to have used his amp at a 2 ohms load without any issues though. even if, again, I'm fully aware Ampeg says it's a minimum 4 ohms load.
Now, as I said, I'll try that, not tour that way.

Just bought a 7pro here on tb. It was bought by the original owner as a new in box June 2021. I’m hoping it has the updated components. Also is there any warranty for me or am I out because I’m not the original owner but I do have a copy of his receipt from reverb. Thanks.
