Harley Benton HB-20B

I bought this Amplifier with a combo of Electric bass, strap and standing equipment for the bass. Without being a professional bass player, I would say this excellent for beginners regarding the quality of sound, volume and the rest of effects. It is quite cheap and works perfectly fine in small places such as your private room or even bigger ones. I used it in a
experimental performance in a quite big space and I wasn't disappointed, neither the audience. I totally recommended this as a starter pack.

*The only negative part is that Aux input stopped working after a while and the headphones output didn't work from the beginning.

I would say that this is a valid option if bought as part of bass-bundle or something like that. Price is low, but so as the sound quality coming out of the speaker. It's usable as a bedroom amp, but the size of it, and especially the depth is not that great (which is expected for this speaker size and cabinet).
Aux input and speaker out I find most usable, as the sound there is decent, and it's great for practice. Overall considering the price, this is a usable peace of equipment for practicing through headphones, and if you want to let some sound out just for fun, but don't expect much more from it (if on a budget or in doubt if you will stick to the instrument, this is a decent buy...was my case...otherwise look for something with a bigger speaker and more expensive, I think it will make a significant difference in usability and overall experience).

Pros:
- Lightweight, AUX in, Headphones OUT, decent build quality

Cons:
- Small speaker, lacking depth, speaker not great tone, and burping on higher volume

Well, I've got to be honest, this is not the best bass amplifier. There's a noticeable lack of bass and I think that's due to the small speaker size (correct me if I'm wrong). Of course, you don't necessarily need to have a lot of bass depending on what kind of music you're willing to play but bear in mind that this issue limits the number of applications.

On the other hand, I did like the built-in compressor. Man, this thing tightens up the sound. If you're on a budget as I was at the time, certainly give it a try, considering that the compression feature could incline you towards liking this amplifier.
