### ⭐⭐⭐⭐⭐ Quality audio
*by J***E on June 23, 2025*

It’s a great amp for creating content with quality audio.

### ⭐⭐⭐⭐⭐ The sweet sound of a tube amp!
*by B***D on November 10, 2024*

Perfect for feeding into a combo amp, or even as a desktop practice amp! Sounds so good!

### ⭐⭐⭐⭐ NO, IT DOES NOT PRODUCE SOUND! (But is probably great at what it does)
*by C***R on June 22, 2025*

Being new to gear like this, I thought I was getting a little practice amp. Why? Because I typed in "practice amp" and this came up. 50w seemed crazy for something so portable, so I asked AI chat assist if I could use it as a practice amp, it said "Absolutely!" and went on to sing its praises. I even watched a few glowing video reviews about it which never showed or mentioned it was an amp-head, a kind of PRE-amp, not a practice amp. D'OH! After purchasing it I suspected I made a mistake, so I asked AI if it could be used as "a stand-alone practice amp." The answer was then, "No!" followed by an explanation that this requires an amp to use. D'OH! I tried to cancel the purchase but it was en route. When it arrived I was seriously tempted to open it, play with it (using my amp!) but I knew I'd probably want to keep it because of GAS (Gear Acquisition Syndrome). Judging by the box alone, the thing must be tiny but mighty because it has real weight to it. That's a good sign when it comes to things that amplify things. Quite substantial for a pre-amp gizmo. But this isn't a review of the product! I wrote this intending to alert those, like me, who are noobs to the bass and typed in "practice amp" and this was the first thing to come up to consider. [btw: I then bought the Joyo DC-15B and it was exactly what I was hoping this was. I submitted a good review of it if you wanna look for it.]
