The amplifier is great looking and sounding. I’ve played my acoustic electric guitars through my other electric guitar amplifiers, and could never get the sound that I wanted. After receiving this, I plugged in my Ibanez Talman and was very pleased with the sound of the amplifier. Now the guitar sounds like it should plugged in. The reverb adds just the right touch to the sound. overall I’m pleased with the amplifier. I was going to buy a fender acoustasonic amp until I saw this amp. Happy with my choice. All this said there is one thing you need to know that I did not notice in the description. If your guitars have active pickups you have to plug into the microphone input .Which means you can’t play the guitar and sing through a mic at the same time. Unfortunately, my acoustic electrics have active pick ups so I can’t use them and the microphone at the same time. I do have a portable PA system, but I bought this in hopes that I didn’t have to carry that thing around anymore. but I’m just happy to get the sound and tone that I’ve been wanting from my guitars. It is a very well built amplifier, and the solid wood is beautiful. It was fully charged when I received it and so far with about four hours of play on it I haven’t had to recharge it yet. The indicator showing it’s still a full charge. Also, if you’re looking for a bag to carry it in, I found one on Amazon. The brand name is Lifewit. It’s actually an insulated lunch tote, but it fits perfect. Has enough padding to protect it some and makes it easy to carry around. One more thing, make sure you have a 5 V charging block or it will not charge. The old iPhone chargers won’t work. Also makes my electric ukulele sound excellent

Have an aging Fender and was looking for a more modern amp. This little am is so light and portable while still having a great output! It has a cool angle for a monitor, but is powerful enough without squelch. It seems to have a lot of play time on one charge and can be charged with a standard cell charger. The input options give a spot for a mic and a guitar with separate volumes. I use this with a pedal and it can handle clean and dirty sounds with ease. 100% portable for an outdoors gig or something that takes place in a spot with unreliable electricity as well! Great price as well!

It’s a nice little amp. Appears to be well-made, solid box, well engineered. It’s like playing through a Bose speaker with an amplifier in it. Limited volume, but good sound reproduction of guitar 🎸. The only reason I would take one star away from the review is that it should have some kind of output for headphones, as it is a practice amp, not a performance amp. I like it.

A good inexpensive portable amp for guitar and dynamic microphone. Decent sound from a small portable box. No hum from the guitar input, as often happens. Easy to use, Good battery life, works well with Bluetooth. I haven't tried the RCA outputs but the headphone jack works. Great for practice, picnics, small gatherings.

Very pleased with quality build and warm sound of this little amp. Has an extra 5 watts of power and an inch larger speaker than my previous small amp. I believe it’s a bit smaller and weighs less too. The angled speaker when on the floor is appreciated. I play fingerstyle ukulele. My only complaint is the brown background with gray labels. Hard to identify which knob is which. I don’t use amps constantly and like labels that are easy to read, so I made my own black/white ones. This amp is perfect for all my needs and quite attractive w/ the wood look and fabric.

Awesome sound in a small package. The reverb option is nice. So far I've used it about 3.5 hours and only used 25% of the battery! Very impressed. Being able to Bluetooth your phone to it allows you to play along with music!

This is a really good sounding acoustic amp for small to medium size rooms, natural sounding and looks to be well made and simple to use. So far worth the price paid. Battery life seems good so far.
