Review: Awesome purchase - It does exactly what I was looking for. Great for practice without disturbing others in the house. Has a 3.5mm Jack imput for backing tracks, and a pretty loud output with two separate pots for output volume and gain. Also a switch for chorus effect. The effects level is not adjustable though. Battery life is very good, I've been practicing for two weeks almost everyday for 1 hour, some days over an hour, still on it's 1st charge! All in all, great value... and everybody at home happy as they don't have to hear my bad playing.
Review: Not too fancy, just the job. - I bought this item because of the review I saw on desertcart stating that it was good for bass guitar tones, which is true. The overall sound is OK and enough for just practice. I won't go into the sound too much because it's not that great but it's loud enough to use for having a noodle. I plugged my phone into the aux point and headphones into to its slot and happily played along to some music. The bass from the phone was just enough to pick up the sound and wasn't imposing on what I was playing. It plugged in nicely to my guitar which is a yamaha with the jack point on the underside, which didn't get in the way sitting back on my sofa. Leaning forward though I wouldn't expect it to last long unless I was sat on the edge although this would not be a problem if the jack was on the front. It took about an hour to charge up completely from my laptop which was indicated when the lights stop filling the bar. The build quality is sufficient and nice and light. The jack points are nice and tight so your wires will stay where they should be. Like I said, I wasn't looking for anything to fancy and this is just the job for a practice session with headphones.

## Questions & Answers

**Q: Does this work with bass?**
A: Yes, it does. The US Madness is originally designed for bass. But after getting the prototype, we found that it sounded surprisingly good with guitars. It has that Twin vibe in it. That's when we decided to market it as a guitar thing. But it can definitely work with bass. No problem about that!

**Q: How do i get rid of rhe white noise in the background?**
A: i had the same issue with my old smokey amp.  i used a set of head phones with an inline volume control to pad out the background white noise.

**Q: Does this have any distortion?**
A: I don’t think so. Haven’t played it in awhile. I was super happy with it as far as the amp. Worked great!

**Q: How can this have 2- 12 inch speakers?**
A: It can power an actual speaker cabinet. But it only produces the amount of currency for powering your headphone set. So if you jack it up directly to 2-12 cab, it will only be the bedroom volume level. I mean that's as far as it can go. 

But if you put into a power amp device, and then jack it into a cab, then it sounds like the real deal! I mean this device is essentially an amp simulation thing. If you combine it with a power amp, then you've got your rig. 

We don't have a 212 cab at hand. But we've done the test to 112 and 412 cabs. Works as I described above.

*by L***. on 11 February 2019*

What a great little headphone amp. Bit of hiss when the volume is up high on the amp, but just dial that back and crank up the volume on your guitar and it's fine. Quite an effective reverb too. Pair it up with a decent set of headphones and this will surprise you. Very happy.
