  • Great Buy!
Style: 30 Watt
Great buy. So far, I have used this as a blue tooth speaker and with my guitar for lessons. I love following along with lessons on my phone and have music in the background to make it sound great!

  • Rockville 10W Amp
Style: 10 Watt
Was not sure what to expect with a smaller amp. I have another that is more of a toy. This is not a toy! This is a real full featured guitar amplifier with surprising sound and controls. I dusted off the old Les Paul and this fit it perfectly. Just practicing but, definitely could use it for a small gig. At this price point it was well worth it. Good support too with links to videos that explore features. Very happy with this one! ... show more

  • Nice little amplifier
Style: 20 Watt
This is an entry level amplifier, that has decent clean tones, and the overdrive is OK for this price point. The Bluetooth feature is a bonus for those that want to play along with music on their iPhone or other Bluetooth device. Only reason for the "4" rating, is that the amplifier arrived with cosmetic damaged to the face. ... show more

Style: 20 Watt
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

  • Tinny sound but might be good for some.
Style: 20 Watt
For me, there is no point in paying 65 bucks for this poorly and tinny sounding amp when I can have a decent modeling amp like Fender Mustang for $150 that has tons of presets and emulations and can connect to and be controlled, if needed, through a computer. This amp essentially just has two line-in ports and a built in bluetooth. While it doesn't buzz that much from the interference from other electronic devices, it's sound is actually not much better than of a $15 Joyo JA-02 mini amp. For mere practicing of just playing a clean guitar, the cheap Joyo or similar device will be all you need and there is no point of paying $60+ for a sumilar experience. If you really want an affordable amp that matters, buy a modeling amp like Fender Mustang, or slightly more expensive Line 6 Spider V and enjoy tons of models and emulations. As for bluetooth, you can always buy a small transmitter/ receiver for 10-30$ and enjoy the bluetooth with any of you devices (plus you might like the cord-less convenience of having a bluetooth dongle while flying in an airplane if you have bluetooth earbuds). Even if this amp cost twice as less, I'd still not see a point of having it or similar small amp, merely because they are somewhat heavy, so you would not really travel with them (and most of them, like this amp, need a power source and do not run on batteries or recharge). Still, some users may like this one. It actually is built quite well and its speakers don't seem to buzz on hight volumes or with basses dialed all the way up. I did not find too much use for its overdrive button because it makes the sound too unpleasant. And the gain knob is too sensitive and adds too much distortion too quickly. ... show more
