Harley Benton Rockplug Classic Rock

I bought this headphone amp to solve my lack of an actual amp because I live in a small apartment where playing with an actual amp would be a little too loud, and I was done with practicing with just the acoustic sound of my guitar.
This little device is a good workaround for not having an actual amp, and the sounds are pretty nice, especially if you turn the drive and tone down, it can produce a somewhat clean sound if that's what you're looking for. When the drive is turned to eleven, it can be a little too gritty and aggressive, making the sound of the guitar a little muffled and pixellated, but playing around with the amp's and your guitar's volume and effect controls fixes the issue.
A great feature of this one is that it has a rechargeable battery, which was one of the features that made me choose it in addition to its low price point. It's small, neat, and useful for playing without drawing too much attention to yourself while using the full potential of your electronics, totally would recommend it to everyone!

The first one I got was unplayable with a super loud bee sound and static.
Thomann costumer service was amazing and scheduled delivery for a new one. The second one is much better and is usable but you can still hear some small bee sound that can be annoying for some people. I suppose that for 15€ you cant expect much more. The features and battery are really good, the sound of the guitar is quite nice and do what you would expect. If you want high quality audio is not for you go for a spark go ( I try it and is amazing but is 130€ not 15€) if you want some small cheap gadget to plug your headphones and practice and are ok with some noises then for the price is quite good.
I'm not completely satisfied myself with the product but it allow me to trust on Thomann costumer service after the 10/10 service they provided me, they become my main music shop after that.
To summarize for the price this gadget is amazing, and it does what it say it does but the quality of the audio goes with the price.
So decide if you want to spend more for better Audio or this does what you want. I been playing guitar for a month and I use it to practice and for that it works.
