Very nice amp! Has a headset jack.
This review is on the wrong product. It is written for the DM30 not the DM20. Both are nice products but the DM 20 does not have a headset jack. ***************** I like it! This amp has plenty of power and the headset jack that I needed for my electronic drum kit. I can balance the inputs and get just the right sound. Definitely recommend. The DM20 watt amp does NOT have a headset jack.

Totally worth it 👌
This thing can do more than some standard 20 watt speaker. This thing can make my electric drums rock the house. It's LOUD!!!!! I mean, don't point it it at your ears when you play. Love it 😀

Does the job.
I'm giving 5 stars because it's good for the price. I like the Bluetooth capability. Not a lot of bass response but works OK for my practice at home. Using it for my electronic drums. Higher quality come with a higher price.

Great sound and great value
I use it for my electronic drums. The sound is excellent and the tone controls are very helpful in getting the sound where you want it. It’s an amazing value.

Great amp for low budget
This has a lot more loudness than I expected, booming bass, and that’s with it turned down halfway in my garage for band practice. It takes a little bit of messing around with the dials to get it tuned in but I love it! Worth the price for sure.

Started breaking after light use. Ok sound quality when working.
Sound quality is pretty mediocre but it was cheap when we bought it. Performance wise this is probably a 3 star. (Though the price has gone up 25% in the past year.) reliability is probably 2 stars because it shorted out randomly when I turned it on about a year into owning it after light use. Sometimes it acts like a paperweight sometimes it works. This is cheap trash really given the sound quality and the reliability but it is priced pretty cheap.
