I have only used this unplugged through its on board speaker. It has a fair amount of drum beats and very usable ones no matter the genre you pick. It has a tempo dial and volume. I got mine on sale or might not have bought it. It's definitely worth the sale price . It's very basic and that is exactly what I was looking for. Just something to jam my guitar along with , it helps me creat riffs . Riffs just flow out of me when I play with a drum machine and that's why I bought it. I've used apps and built in drum machines on my processors but I wanted something simple and portable. It can run on batteries and that's a huge plus . I just use it anywhere in the house and grab a guitar . I use it for practicing covers too but mainly for my own creative purposes. It's a great musical companion.
