Sound fidelity is good. Gain distortion works well. Also used as a preamplifier to audio system amp with good results.

I wonder if there really is a difference in "Tube", "Metal", "English Channel", etc. sounds. Some listings show assorted types without ability to specify. This one said "Tube" and that's what arrived.

Note that batteries need to be replaced. I might prefer built -in Li battery, USB chargeable. Matter of personal preference, I suppose.

The product was made and shipped directly from china. The arrival date on amazon said it would take approx 1 month to arrive; it took about 7 working days. I was happy with the early arrival to say the least_

I bought this amp to use with headphones, so I could play as loud as I want without bothering others.

It has tone, volume and overdrive adjustment dials; However, the volume dial setting is factory set so loud (on low) that using the gain overdrive is impossible to use unless you want your ears blown out!

I guess you could sayI got what I wished for-LOL.

The unit does work, with no "fuzz", but it does the job it was intended for.

First off I'm a drummer. But I do find this mini amp sounds good. I've been playing through a Schecter C-1Exotic. The mini has a nice gain crunch that I can barely tell is not a tube(atleast heard through cheap headphones). Unlike the review read earlier, the batteries seem to be holding up decent. I have ear bud type headphones. Nice for under 20$.

Gave this too my father, he uses it all the time. It's simple and effective, also cheap. Sound quality is very good and loud. Battery life is also good.

Inexpensive, highly portable, produces good sound.

The second one I own. Like my other one, in order to get sound from my earphones I must retract the mini-plug just as bit to obtain electrical contact however, this is not a problem.
