Review: Awesome purchase - It does exactly what I was looking for. Great for practice without disturbing others in the house. Has a 3.5mm Jack imput for backing tracks, and a pretty loud output with two separate pots for output volume and gain. Also a switch for chorus effect. The effects level is not adjustable though. Battery life is very good, I've been practicing for two weeks almost everyday for 1 hour, some days over an hour, still on it's 1st charge! All in all, great value... and everybody at home happy as they don't have to hear my bad playing.
Review: Not too fancy, just the job. - I bought this item because of the review I saw on desertcart stating that it was good for bass guitar tones, which is true. The overall sound is OK and enough for just practice. I won't go into the sound too much because it's not that great but it's loud enough to use for having a noodle. I plugged my phone into the aux point and headphones into to its slot and happily played along to some music. The bass from the phone was just enough to pick up the sound and wasn't imposing on what I was playing. It plugged in nicely to my guitar which is a yamaha with the jack point on the underside, which didn't get in the way sitting back on my sofa. Leaning forward though I wouldn't expect it to last long unless I was sat on the edge although this would not be a problem if the jack was on the front. It took about an hour to charge up completely from my laptop which was indicated when the lights stop filling the bar. The build quality is sufficient and nice and light. The jack points are nice and tight so your wires will stay where they should be. Like I said, I wasn't looking for anything to fancy and this is just the job for a practice session with headphones.

## Questions & Answers

**Q: do you plug it into a guitar? / is it like a speaker?**
A: NO! I thought it was that. Is like a mini amplifier need speakers. Has a mini plug out for speakers or headphones. So, was kind of disappointing. But works.

**Q: Can you use it while charging it?**
A: I believe that it can be used that way. But I suggest you not. Besides, it doesn't take much time for you to charge it to a level allowing  you can use it for hours.

**Q: Do i need studio headphones?**
A: can make studio headphones work with 1/8 to 1/4" adapter.  ~$5

**Q: Will this work on my godin king pin f hole hollow body ?**
A: I am not familiar with the godin, but if it uses a standard guitar  jack, then the classic should work with it.  The plug on the classic is the same size as a standard guitar cable.

*by L***. on 11 February 2019*

What a great little headphone amp. Bit of hiss when the volume is up high on the amp, but just dial that back and crank up the volume on your guitar and it's fine. Quite an effective reverb too. Pair it up with a decent set of headphones and this will surprise you. Very happy.
