This little amplifier provides a lot of value for its price point in my opinion. I have used it with a keyboard, and it works great. The unit has two inputs, so I could also connect another instrument at the same time like an electric guitar. The sound quality is very good, and I like that there is adjustability of the sound using the three band equalizer for low, mid, and high "tweaking" lol. I also like that it has a headphone output with its own volume control and a port built in to set it up on a speaker stand if desired. Overall, I like everything about this unit, so I would not hesitate to recommend it. Therefore, it receives five stars from me all the way!

This is a very versatile amp. You can use it to monitor electronic drums for practice or a practice amp for guitar or microphones.

This has a good amount of volume and can be speaker stand mounted or used as a floor monitor.

Bluetooth connectivity is nice for adding your favorite song during practice making this one of the more versatile amps.

This Coolmusic 30W Personal Monitor Amp works well. At the price point, it is a good value for the performance. It is a smaller, compact amp - very portable. The Amp has 2 inputs with independent volume control and independent headphone output. Plus it has Bluetooth - this is very fun and cool to use. We have used it with a keyboard and it works well. The amp is well made and easy to use, happy with its performance and size.

I got this speaker for my husband to be able to attach to all his guitar equipment and have a small set up in the bedroom . It's great for keyboard - bass- drums -mics - or guitar. It has a decent sound and makes a great practice amp.

This is great piece of gear for the electronic drummer. I couldn't believe how punchy it was with the drum machine going. I was actually looking for a small practice amp for my synthesizers and I ran across this thing. Am I glad I did. It sounds real good.

It's extremely well-built and it gets incredibly loud without any distortion. It's got a good heft to it and there are two aluminum grab handles to help you out. It's got both a 8" woofer and a 2" tweeter for a balanced sound but, of course, it is a little bottom heavy. There are two inputs with separate volume controls and three standard tone knobs. There are no built in effects. You also get a Bluetooth connection, a USB port and a headphone jack. The case is covered with black vinyl in the pebbly "guitar amp" pattern.

It would be a shame to use this just for electronic drums; it's way more versatile for just that. It would perfect for a solo guitarist or a string bass player in a small club or restaurant. With the Bluebooth connection and your phone, you can even add some prerecorded backing tracks. Add some mikes, a small mixing board and another one of these speakers and a small combo can get real loud. Bluetooth also makes it suitable to use at party or a barbecue with preprogrammed music from your phone.

One of the nicest features, though, is its ability to be quiet. There is practically no hiss from the speakers, even with the volume and treble turned all the way up. This is nice little box that I'll use to record some of my synths live, it makes them sound that good. And to top this all off, this amplifier is an incredible bargain. Coolmusic has been making amps for awhile and people seem to like their products a lot. I'm glad some folks are still making quality equipment that an ordinary musician can afford and be happy with. I really do hate to gush, but this thing is more than worth it. Do not hesitate to buy.
