Alone and with Helix
Boddumblues 05.03.2018
I got this unit and hoped it would work for me, and it does.
I wanted the mic sim and line out to be before the the dampening,
and thankfully it was easy to convert it to this.
I did not want the line out and mic sim to follow the dampening.
I added a 25 k pot on the mic sim out to add more control. Now I use it with my Marshall 6100 head and a VOX AC-10 (with a speaker in mod), and am quite pleased. I do find that mic micsim signal kind of collapses. But when using the linesignal through a Behringer Ultra-G Di. box I have a beautiful full signal. Of course it would be nice to have the micsim do it, but the Behringer just sounds better in every way. For the price of the PA-100 and the Ultra-G and my mods, you have a package that is hard to beat. ;-)
I do run presence on 100% on the 6100, and raise the treble on the AC-10 but it's fine.

What this unit allows for also, is use of the lineout in different ways;
1: Load your amp into a Helix.
I have patches in my Helix based on a VOX AC-15, but if I want to have my real AC-10 replacing the modelling amp, i can patch it in via one of the loops (line level) and it works like a charm.
I hear my amp in real life, the FOH gets a lineout from the Helix with the real amp through the Helix, and then I play with IR's, mainly Celestion Blues and Golds - sweet!
2: Lineout + IR's
The lineout without the micmod can have IR's added (Moer Radar etc.) to add flexibility and quality to the sound. Even using my Digitech RP-155 just as a cabinet simulator opens up a lot of sounds.
So there are a lot of sounds waiting to be heard.
Also in a DAW. Cheers ;-)
03-07-2018 Update
I tested running a JOYO JDI-01 from the line out, and man what a difference to the mic-mod out it is, it really works now, the cab sim on the JOYO is sooo much better in fidelity, the AC-10 really shines through the mixer now. It also beats the Behringer in clarity (the Behringer only has 1 cab sim, a 4x12, the JOYO has a 2x12 combo sim and a 4x 12 sim), I am very very pleased with this new dicovery!

Well priced alternative to many more expensive non-reactive units..
Ignateous 17.05.2023
If you can’t justify paying many times more for a “Reactive” load box, but want an easy, simple, economic way to avoid upsetting housemates and neighbours, then this does the job well..

I was tempted to give it 5 stars, because it seems unfair to mark down such an affordable piece of gear for having slightly cheap feeling inputs/outputs.. But I wouldn’t want anyone to think they’re getting perfection at this price..

all i need
brert 30.11.2021
For the price, you shouldnt complain about anything of this device. Yes a 500 euro unit has more options(?) and sounds a bit closer to the original sound of the amp (like the rockcrusher i compared it with) but is that really worth the extra 430 euros? I'd rather have some cool pedals of guitar for that :-)! So in my opinion totally worth it! does what it needs to and for my (non-professional) use, all i need. Now i can play my ac30 without causing a local earthquake!

Seems to do the job okay, although it does have a noticeable effect on frequency responses at the extremes. With some dialing in and balancing between master volume and this it can soak a decently loud tube amp (joyo mjolnir, says 15W but I suspect more) and cut it back to room volumes where people can still have a conversation over you.

HB PA100
InDecember 24.12.2019
I use the HB power attenuator to tame a 60 watt Engl Fireball tube head to levels suitable for home recording. It does exactly that and you get some extra nice features, like adjustable line out and xlr out.

The silent fan to cool the resistors is indeed silent but only once it's spinning at full rpm, when it starts spinning it makes a little squealing noises. Not loud, but noticeable.

As a test, I maxed out the Fireball and both attenuator and amp survived, while retaining a usable tone. I wouldn't try this on a 100 watt tube head though.

Only con I found thus far is the fact that there is no bypass switch, meaning once connected, you're attenuating.
Pro's:
Cheap, sturdy, much features, can't go wrong with this. And of course the usual great Thomann service.

Good value
John Mc 22.06.2020
Was VERY hesitant about a "cheap" attenuator to use with my Marshall SC20H . It's definitely a great buy. very simple to use . Not quite sure about the line out function as i cant seem to get it to work but its not a big deal as i use my line out from the Marshall.
This was really bought to mute the cab or adjust the volume if needed.
is it the best attenuator in the world ? probably not but is it worth $100 ? DEFINITELY !!!
Now its on to the HB cabinets.

Use as a DI box
Ghoward 18.01.2020
I bought this mainly to use as a DI box so that i could get the full potential of my amp while playing silently, and then i bought a pair of monitors so know i can run my amp into this and then into my interface and pc and can play through my monitors for recording and monitoring. It is a perfect device for my uses. I do not notice any sound degradation with using this

Works well
Richard 1961 24.08.2020
Does what it is suppose to. Does affect the sound quality a bit. About the same as switching the amp to a lower power setting.

As good a solution as there is for wanting to drive a tube amp hard without being too loud
