Tone King Imperial Tri-Tube Preamp

Bought this a bit on impulse for trying out in my home studio. Regretted it at first as I should really use my money on other stuff. I have a Tone King Gremlin, which sounds great on my recordings, but I usually need to record DI and reamp afterwards, which is a tedious process.
I’ve tried a lot of software amp modellers and found noone that has impressed me. I’m mostly after a clean guitar sound.
The imperial preamp pedal sounds like an amp and the cleans are really great. I can actually record through this and it sounds just as good or even better than when I record through my Gremlin with a Royer mic.
Updated impression:
I was a bit disappointed with the tremolo at first, but now it's hard to not have it on in a rather subtle setting. The reverb is also really nice and is always on.
My only complaint is that a couple of the jack connections seems a bit loose, depending on which cable I use. I keep it connected in the studio all the time, so not a big issue, but if I were to use it live it could have been a problem. That's why I give it 4 stars on quality and handling.

I own a Tone King Imperial Mk2 amplifier, which is by far my favorite piece of gear, but I often practice at night, with headphones on, and I love to sound good even when I'm really just practicing or fiddling around. I have ToneX, I have Quad Cortex, many plugins, but none could give me the feel I have when I practice on a real amp.
This preamp pedal simply mops the floor with the Quad Cortex, ToneX, and every other digital stuff you can buy. It sounds incredible through headphones. It feels great, the response is amazing, the tone is just beautiful. I can use my whole pedalboard with it, even at night, and since it has an FX loop (as opposed to the amp), I can actually shape my tone even further.
I have absolutely 0 regrets for buying this, this became my absolute favorite for low-volume and headphone practice sessions. It really can't get any better than this.
