    • Nice little amp at a nice price!
Style: 20 Watt
I have been playing mostly acoustic guitar for 50 plus years and I recently bought a Squier Classic Vibe 50 electric (nice guitar by the way). I wanted a small practice amp and was originally looking at a small Fender amp. When I saw the bluetooth, overdrive, and delay at this price point I decided to give it a try. I am not disappointed at all! I bought the 20W version but mostly use it with headphones for now. This little guy is pretty versatile with various sounds and has a lot of volume. I love the bluetooth for playing with backing tracking. It would be nice if the bluetooth had its own volume and tone controls, but it doesn't. It still works pretty good. I may upgrade at some point, but for now this amp is perfect for my use. It may be all about expectations, but if you're looking for a practice amp with nice features at a reasonable price I would recommend it. ... show more

    • It's an amazing amp
Style: 20 Watt
The reason I give this a 4 star instead of 5 is my package was late and was delivered by FedEx. This amp sounds great, I love the Bluetooth option the most. The Bluetooth option allows me to play songs along with the originals to make sure I'm getting the right tone and feel of the song. And if one day you decide to stop playing guitar you can just use this as a Bluetooth speaker. I love how it has the option for delay and it actually sounds pretty cool. I'm confused on the two channel inputs since it didn't change my tone and I read that's what those are for. I also love how it has a clean channel and a non clean channel. The first amp I bought was a tiny fender amp that didn't have that option. It stopped working after a few months and so I needed a new, cheap, amp. Needless to say this amp will encourage me to play my electric guitar way more. ... show more

Good acoustic practice guitar amplifier Good sounds for it's size, all buttons work as they should, 2 inputs is a plus, Bluetooth works great. Wow, the more I use the guitar amplifier with my acoustic/electric guitar in one input and microphone in the other input the more I like it. I would buy again. ... show more

    • Great Deal For The Money
Style: 20 Watt
For the money a great little guitar amplifier. Takes a little time to adjust to your guitar and playing type but once done a great little dynamo to play at home or take on road when travelling. You don't get the punch like a 50 watt amp but that was expected.

    • I LOVE. but, sound could use a bit of work
Style: 20 Watt
I really really like it!!! Just got my first ever amp and electric guitar and for a first amp it's pretty nice! Seeing as this is my first, I'm not very well versed in amplifiers and their sounds and qualities and overall functionality. That being said however, I had much higher expectations from this item because of the reviews appraisal of it. It does it's job! Functions very well, I love the Bluetooth and headphone jack feature, as well as the dual input feature that'll be great to practice or jam with friends. The sound gets pretty loud. Not as loud as I was expecting, but It packs a punch that I have to have the volume on like 2 with the distortion up just to be able to play semi-quietly in my room lol. The clean channel is obviously quieter at full volume but it still gets really loud. My only issue is the sound quality could be better. Honestly much better. Its nothing horrible! It sounds quite nice! And while this is a "cheaper" end amp, even for almost $70 I'd expect a bit more quality sound. I plan to replace the speaker eventually as I'm just going to use this amp as a practice/jam session amp and maybe take it to small/medium venues if I can get that far. I think it's perfect for practice and travel venues where you don't wanna lug around big or expensive equipment. I do love it, and im sure with a better speaker it'll blow me away. For what you get and the price, i highly recommend EDIT: I COMPLETELY FORGOT ANOTHER THING ABOUT THIS AMP. The power cord that plugs into an outlet is SO.SHORT. idk if tahts common among amplifiers but like it's unreadable short omg. My room is tiny, so I like to sit at my desk to play guitar. But the amp can hardly even meet me halfway here and im maybe a maximum of 5 feet away from where it's plugged in. So that's annoying a bit. Also for me personally I love a rock and metal and heavily distorted but also crunchy sound, and it is kinda hard to get that sound accurately out of this haha. I probably just have to mess around with it a bit more, but the cleaner tones sound amazing on this amp, but if you're looking mainly for distortion like me, this may not wanna be your very first pick, but definitely nowhere near the last. I love this little thing ... show more
