Had a drum machine in the 80s. It sounded like an 80s drum machine. Then my wife bought me one as a present 15 years ago. Complicated and clunky to use and it was all Crash, Boom, Bam. Then I recently heard about this one. First of all, I’m a fan of Boss products. I have their Acoustic Singer Live amp and it is fantastic. Watched some videos and read reviews. My wife gave me a gift card for my birthday, so I sprung for this. It is fabulous. Organic, acoustic sounds (no crash, boom, bang) SUPER EASY user interface, lots of variety, as many as seven instruments at a time (if you count the metronome - you can choose a nice wood block sound). I was able to start using this right away and with quick glances at the very clear manual, I was navigating my way around. I used it for a livestream show the first week I had it. It’s so much fun to play along with, I’ve been playing more. You know how they say “practice with a metronome”? Well, I never could because it was boring. But with this I get a steady beat that is fun to play along with. With the Boss unit holding a rhythm, I’m taking more chances, trying more licks and fills. By adding rhythm parts I have found that some songs that have eluded me, that didn’t (at least with my abilities) come off well on an acoustic guitar, now made sense, sounded full (but not too “canned” or orchestrated). I play a lot of Americana/folk/country and most times a simple cajon rhythm is all I need. I’ve added simple rhythms to songs that I normally just fingerpick. The rhythm partner gives plenty of options to add something subdued and tasteful that doesn’t overwhelm the finger picking. Okay, corny as it sounds, Rhythm Partner is really the right name. It works as a partner, so smoothly and easily, I don’t know if I’ll ever want to play without it. I should add that I bought the Boss FS-6 foot pedal so I could control it hands free. The pedal seems expensive for a dual latching controller, but it’s worth it. The Rhythm Buddy gives you lots of options for pedal settings: instrument trigger, fade out, etc. Once again, just an example of the thought that went into the device. I have the right switch set for start/stop, and the left for tap tempo in case I need a beat on the fly. Just a great rig altogether.
