TS20 Bass Combo Amp -20W Suitable for Bass Guitar…

The media could not be loaded. I was in the market for small amplifier for use with keyboards and synthesizers when I found the TS20. After doing some research, the features included on the TS20 were what I was looking for and then some, so I placed the order. After receiving, I was surprised how compact yet hefty and solid it is. I proceeded to try a few different keyboards, Yamaha PSS-480, Korg Monotribe, Arturia MicroFreak, PO-12, all sounded excellent and is a welcome improvement over the keyboards built-in speakers with it's ability to produce deeper bass. Next, I gave the Bluetooth option a try. The TS20 paired quickly with my Samsung S24 Ultra and sounded great. I was also able to pair with a turntable that also sounded good. The volume is sufficient without distorting, but it will if you push it. It also has a nice punch while playing electronic drums. One day I may try a guitar with this amp, but for now, it definitely meets all my expectations as a solution for my keyboards. This small 20W amplifier doesn't disappoint and is a great value, I'd surely recommend getting one.

The audio quality is acceptable for the price range. Its compact size makes it a fine option for casual play on small spaces. Bluetooth functionality is easy to use and sounds fine as well.

TS20 Bass Combo Amp -20W - $99.99Solid and well-built practice amplifier that works well for both bass and electric guitars. It has decent tone controls, Bluetooth functionality, and can produce a clean sound even at high volumes. While it's a great entry-level amp for home practice or small settings, it may not be suitable for gig-style performances or larger venues due to its limited power.

I really wanted to give this bass amplifier 5 stars; but, although it's sturdy and light and sounds really good and the Bluetooth feature is great, it rattles and distorts so badly at the low bass guitar string frequencies that it can only be used at one-half the gain/volume setting. I had hoped to use this as a light and portable amp for small group practice sessions, but the noise is too distracting. I'm anyway going to keep it and use it for home practice with the Bluetooth, with the amp close to me so I can keep it at low volume.

This is a very cool little bass amp from Coolmusic. It’s great for bass, but it’s also a pretty good clean amp for guitars. The tone controls are pretty good, with each frequency band actually making audible changes for both bass and guitar. I have a Fender BXR 15W bass amp, and I would say this CoolMusic TS20 compares very well to it, with the TS20 maybe being a bit better for both the lower price, smaller size, and the addition of Bluetooth.The gain knob on the TS20 is a bit odd, and ramps right down to zero – so no matter how high the master volume is, you won’t hear anything until you put the gain up a bit. I’m used to guitar amps in which a minimum gain dial passes a perfectly clean signal, and then can be turned up from there. And my BXR doesn’t even have a gain knob. However, this amp never goes into overdrive or distortion – it stays clean all the way up to full volume. The full volume (gain + volume maxed) is pretty loud for a 20W amp, and you can really see the speaker grill cloth moving like crazy with the lower bass notes.I tested the Bluetooth, and it shows up as “Coolmusic” and is easy to connect to. You can play through the amp while the Bluetooth is playing. The master volume affects the Bluetooth channel, but the gain knob doesn’t, so you can set the ratio pretty easily (I’m guessing this is why this amp has a gain knob – it’s really just the guitar-only volume knob). When you’re playing music through Bluetooth, that’s when you can really tell it’s intended to be a bass amp, as it’s definitely bass heavy without EQing it too much.This amp is also pretty small. Definitely smaller than a breadbox, maybe half the size of my BXR. I’m actually pretty surprised at how much air it can move with just that tiny 6.5 inch speaker. The amp is also very quiet with no input, with no hiss or hum to speak of. The boost/bright button was pretty staticy when I used it (only while pressing it, not all the time), but that’s not a big deal.Overall, I wouldn’t hesitate at all to recommend this as a first bass amp, or even as a clean-only guitar amp, for home practice or playing small venues. It definitely sounds good enough for its price, and gets loud enough. Easy 5 stars – buy with confidence!

First I want to say that this is a very solid and well built mini amplifier. The cabinet is designed so that it delivers or puts out the best sound possible. And that's obvious when you look at the cabinet and how to put together. That's just my opinion.The sound is evenly balanced and for a mini it gets pretty loud I know 20 watts of power is not going to shatter the windows but it does get loud.I like the fact that it also has the Bluetooth so you can play some background music to play along with.You got your basic knob controls for your treble your mids and lows, as well as the main volume control and Gain Control. Then you have your switch for boost and bright as well as a headphone jack for monitoring or listening and extra auxiliary line in and of course your main input jack.It's got a nice little handle so you can carry it around and it weighs roughly about 10 lb or so so it's not that heavy to be lugging around if you need to take it somewhere.Overall this has got great sound it's solid it's well built it has Bluetooth it's just an all-around perfect little practice amp either for your bass guitar or your electric guitar or if you just want to use it for karaoke you have options with it I would recommend it for sure.

This amp has a terrible rattle even when it's turned way down. This happened right out of the box. I do not recommend. I did not return it because I thought I could could adjust the settings to clear out the sound. Now I am past the return window and am stuck. Look elsewhere.
