    • Great little amp for my workbench!
Review Image by Brant E Good
I am a guitar and bass tech, and thus was a great little addition to my workbench for testing guitars as I go along working. Bot has a great reverb anlittle delay and just the right sound for a workbench setting rather than taking on & off headphone amps or getting up and going toy amp room. The sound quality is great for such a small package. ... show more

    • YES I LIKE IT.
I like this amp, and that it is portable, battery operated, rechargeable. The delay doesn’t adjust very well. It doesn’t adjust to just one repeat, it gives you several or multiple repeats. Reverb is good. You get a bit of frequency interference occasionally. But I still like the blue tooth feature for backing tracks from the internet. And the ability to just grab it set at the kitchen table and play. It sounds good, and you can’t beat the price for what it is. ... show more

    • It serves the purpose.I should little practice amp
You really can't regulate the delay. Otherwise, it's pretty good reverb's fine, clean amp. For what it is, it's worth the money, but like I said, the only downfall is the delay

    • Easy to use, sounds pretty good.
Sound is decent-good. Effects work very well. Charging is easy. Needs a handle to make it more portable. Loud enough for a room or office easily.

    • I wanted to like it
I wanted to like this amp. I'm familiar with the smaller cousin of this amp, the BA-10, and I thought that this was going to be that, but better. However, the amp I received is really not usable. I don't know if it's a defective amp or a general sign of the quality but the guitar audio seems to have a permanent aggressive noise gate that kills any sustain your guitar has and gives you very uneven sound. It's noisy when playing, and then drops off to silence unevenly and fairly abruptly. The functions all seem to work. Bluetooth paired quickly but they have loud verbal announcements of "Bluetooth Connected" which is unnecessary and not something I want from an instrument amp. As a Bluetooth speaker it's decent. Not as good as similarly priced music speakers, but decent. The delay and reverb are nice to have and usable. The OTG recording works. Overall all of the features work. But the noise gate or faulty electronics or whatever is going on makes this unusable as a practice amp for playing guitar. It's distracting and it sounds bad and I don't think there is a way to turn it off. Build quality is OK. If you are familiar with the smaller BA-10 amps it looks like a scaled up version, but it doesn't feel as sturdy. That may just be that the amp is bigger but the plastic is the same thickness. For the price of $83 there are much better options on the market and I just can't recommend this. ... show more
