I haven’t tried them but I get the impression the Trickfish head could be in the realm of ultra clean amps. I’d consider pairing something like that with a Barefaced Big Baby for a studio monitor FRFR experience. The Super Compact would be a bit smaller and easier to manage and probably still plenty loud (I just prefer the BB to the SC based on my experience).
I looked at Trickfish. The 1K is out of my price range, but I'm not sure 500 watts is enough. It probably is, but I would rather get 700 just to be safe than sorry. Their 2x10 cab is also a heavier than others I've looked at by 20 lbs.
1) Combo
Rumble 800 combo. Yeah, all knobs at 12 o'clock has some color, but you can tweak it quite well.
It has NEO 2x10 speakers, the whole thing weighs 28 pounds. Has 1/4 power switch for home use as well. Significantly cheaper than your budget. Add another cab for the full 800W.
2) Head + Cabs
Quilter Bass Block V803, pairs well with anything.
Just-out Seymour Duncan amp getting good reviews as well.
The Seymour sounds interesting, but TalkBass, as everyone else, loves new shiny products before turning on them a couple of years down the line. Whenever you asked a question here around 2010 the answer was MarkBass. Then it was Aguilar. Now it's Mesa. There are still some people using MarkBass and Aguilar, but they don't get the universal praise they once did. I skimmed through the Fender ACB 50 thread. Glowing reviews at first, then not so good, mixed.
IMHO the cab is more important, allocate as much of your budget to the cab. I went with Berg cabs CN112 and CN210 (a few years back) and the Berg heads were not out yet so I use a TH500. Yes, the TH can be clean by running the Gain all the way off and then adjusting the Drive which is actually a variable hpf.
Why limit yourself to cabinets made by the same manufacturer as the head you chose? "Clean sounding" would seem to say neutral. I don't think of Aguilar as neutral. It is more Ampeg-ish than most other brands, in my opinion. I have a TH500 paired with a LDS 15/6/1. You don't mention much about application, where and what you play. I find a single 2x10" is the minimum. A 1x12" can work in gentler situations, but if I am spending money, I like to have some headroom. Obviously, if you play different rigs, that helps. I had a Markbass NY122 that I just didn't like. When I played through a buddy's Markbass 102, it was awesome. Anyway, good luck.
I plan to allocate more to the cab than the amp, actually. I want the same manufacturer because not doing so would make me uneasy, although I suppose I'd be fine if I got a Barefaced since they don't make amps. The other reason is that trying different amps with different cabs is hard to do (I could maybe try GK, Mesa and MarkBass in the same store, but not so much the others, although if I bought a Barefaced I could test it in stores), and that being the case, I assume, maybe I'm wrong, that I have a better chance of getting a great-sounding pair if the brands match. For example, I'll assume Aguilar tweaked its cabs to sound good with their amps. Maybe they haven't spent much time making sure they sound good with a MarkBass.
I agree the TH similar-ish to Ampeg, but I didn't think the AG did?
I mainly plan to bring from and to a rehearsal studio on weekly basis that includes two flights of stairs, hence why it needs to be light. It's an alternative rock band (think Arctic Monkeys) with two guitars. I will also be gigging with the band. The other band is a top-40 from the 70s to today, so everything from classic rock to modern pop. I don't need the amp at rehearsal with this band, but will need it to gig.
