Been live giging 3 - 5 times a week for probably over 20 years with my DR3. I don't remember when I bought it, but it has been in my travelling gig box for every gig. I learned how to copy its program patterns to user patterns, edited them and have every rhythm and every tempo any musician could want - Waltz, Blues, Jazz, Latin, Samba, Rock, Funk, Classics, Country, Hip Hop. etc. It is all there. Listeners are amazed at the variety of rhythms available and how I go from song to song. Easy to shift from one pattern to another. I use to use the foot pedal, but have eliminated that because the hand use mode works well for me as a solo guitarist. I've messed with and looked at others, even new models from Boss and competitors. I no longer waste time looking at others. I chose this because it is the best for me. Maybe you too.

If your IQ is 140, it's a wonderful piece of equipment

This is really amazing, but you better have a PHD in audio engineering if you expect to understand everything in the manual. I highly recommend Rolland,s owner's manual DVD if you hope to operate this gear!

Wanted one for years

Yes long ago I wanted a Dr Rhythm , they have changed a bit over the years but this little machine will change your life. It is a rhythm section that will play for you any time any where , with no gripes or ego trips. My buddy and i have experimented with reggae and balads and of course the Chicago Blues setting always get a workout. It has a bunch of features I have not used yet because I have spent to much time just having fun with the programs that it comes with out of the box.

Simple to use and Great sounds

This is a very easy machine to use and, really has a lot of Great sounds and beats. I use this live in a duo with my son, I play guitar and sing and he plays bass. Dialing up a program and setting the BPM takes just seconds and were off to doing another tune. With what were doing there isn't time to twiddle knobs and tweak settings and, that's what makes this unit so sweet. You definately have to work with the machine to find the right program for the song that you want to play but, that is what rehearsal is for. When you find the right one make a notation on your song sheet and, dial it in, it's that simple. You can even change the BPM on the fly if necessary. Simplicity is the big selling point here that's why I use it. I use the Boss double footswitch to start and stop the programs and to add fills if I want, also a Boss single footswitch as a kill to stop and start the program at any time that I want or need to. It's about the closest thing to a live drummer that I have used and, the price wont break the bank either. There are more complex machines with many more sounds out there but, you will run into more complex programing and use, not to mention more cost too. This unit works Great for me and, gives me all I want. We do a large variety of songs from hard rock to bluegrass and this little unit does the job.

Get a DR-3 and Fire Your Drummer & Bass Player!

Sounds cruel, right? I am a solo artist and I do mean SOLO. What if your drummer and bass player are late or just didn't show? That's happened to me before. Not anymore guys. The drums and bass are realistic especially if you use a powerful sound system with enough bottom end. I use it with the Roland SA-300 (350 amps) and have even tried it with the Fender Passport PD-500, (500 amps). Both systems allow the bass to shine and really carry the rhythm. 100 presets cover nearly every style and then some. Great for writing and composing too. Just fill in your melody line and lyrics. Super easy to use and adjust to the tempo and key you want to play in. So much for so little money. Definitely buy one and relax. You can stop worrying if your other gig-mates will show.
