JHS Pedals Little Black Amp

Pedal works fine!
Does its job very decent. I use it as a volume control for my Peavey 6505+ 112 combo and I put it in the effects loop. This way I have more detailed range for the volume on the amp itself.
The only thing I can remark is that the knob does not turn as smooth all around the range of the potmeter. turning from 0 to 50 percent, the knob loses 'smoothness' and becomes somewhat stiffer to turn. From 50 to 100 it becomes more and more smooth towards the 100%.
This does not affect the function and that's the only thing I can remark. In my opinion, great price/quality ratio.

I use this with my Fender HR Deville 60W which is loud as hell (and has no master volume), to tame it when at home. The LBA has done well its job as expected.

Pros:
Simple/cheap solution to a common problem

Cons:
- You could probably build this yourself with a potentiometer if you research a bit on the internet.
- The closer the potentiometer is to its 'zero' (min volumen) you'll clearly hear a degradation in your tone. There isn't any obvious degradation if you have it from half way onwards.

For me, if you're looking for a professional attenuator you need to prepare to spend 30 times more money. But if you're looking to solve your play-at-home-quieter issue, and you don't bother to build this yourself, the LBA is definitely worth the money.

I have a Joyo Zombie which comes in at 20w paired with a 1x12 Harley Benton Vintage Cab and I immediately had the problem with not being able to push the volume anywhere past 2 without it becoming too loud for my bedroom.

The Little Black Amp solves this problem immediately, I cranked the pot on it to the point where i can have my volume at about 12 on the amp and it now sounds completely clear, driven and full, where before with the volume on such a low setting the sound was very bassy and unclear, but this has allowed me to push the preamp tube and create a wonderful tone. Very very happy overall and would recommend!

The JHS Little Black Amp is a fantastic device for just about anyone to have in their arsenal, especially considering how cheap you can pick one up, it's something I use often and for a couple of different potential purposes.

THE PROS:
Simple and effective. The device attenuates the signal right before it hits the power amp reducing the volume of loud tube amps for those occasions when you need to be quiet and still sounds fantastic.

The device can also act as a kind of pre/master volume if you have multiple master volumes for your channels or other preamps which you want one global control for, which is super useful!!!

THE CONS:
None really, maybe some level markers would have been nice. We just used colored pencils to mark our favorite positions, no biggie and way cooler anyway ;)

A GREAT option for those looking for cheap, reliable good sounding form of amp attenuation, would absolutely recommend.

Excellent pedal, JHS quality, super simple and no power, small footprint, your amp and pedalboard will love it.
I thought my amp sounded a bit thin after I could push him during a rehearsal in a studio (Quilter US). After some research, this pedal deserved a try. The volume of the amp is 5, 7 for the gain, which would be unbearable in the living room without this pedal. It sounds amazing, at the right volume (relatives and neighbours could ( / should?) have paid for the pedal :-)
You can read in JHS manual it is recommended to have this pedal only in the effects loop of your amp. I moved the reverb and delay pedals in front of the amp, not an issue for me but something I was not aware of before I got the pedal.
