Can be used for bass, sort-of.
"I believe this is a good value for the money.
Basically, this is a Vox rip-off for way less money. It works. It isn't awesome, but it works.
I actually purchased this for practicing a bass with headphones. This does work for this purpose, sort-of.
This is intended for an electric guitar with distortion and it probably works great for that. There's no shortage of distortion gain.
However, for a bass, unless you're playing death metal, you don't want distortion.
Here's how I was able to get a usable tone (not great, but usable).
Bass pickup volume should be about 1/2 way.
Gain should be all the way off.
Tone - middle-ish. I couldn't get a great tone no matter what.
Volume - all the way up.
Basically, you have to have as little input gain and as much output amplification as possible in order to get a somewhat clean sound. Even with this config, there is still a little bit of distortion but not too bad. It sounds like an old tube bass amp with some input gain.
I wish Joyo would make a bass-specific model of this like Vox does but this unit will work if you just need to hear yourself for practice.
I haven't tested the aux in and I can't attest to longevity although it seems pretty flimsy.
If you're cheap like me, get this. If you want a better quality sound, get a Vox."
Batteries it came with were dead
"Works good but the batteries it came with can't ever power a tv remote the were still in plastic but didn't work."
