I think its magic

Ive tried about every small practice amp you can think of, they all fell short. This on the other hand, is the answer . Im not a big fan of modeling or effects, but these are actually pretty good. teble , bass, mid, and gain? Check. Tuner? check. Metronome and drum machine? check. works for bass, guitar, and voice? check. Ac or dc power? check. Aux in and out? check. Headphone jack? check. Great sound? check. Roland did their homework on this one! A+++++

Roland micro cube rx bass amp

First of all, the size of this amp is so small compared to the amount of volume that comes out with so much clarity, you look at it and say WOW. With 8 amp models and 6 digital effects to play around with you can customize your own sound. An awesome buy!!
Music background: I've been playing bass and harmonica for over 40 years . I own a 67 P bass, aTacoma electric/acoustic and an Ibanez. I usually play these through an Eden 550 head and a 210 bottom but for smaller venues, I use the Roland cube.

An Amp For The Ages (and ageless)!

This is a great product! No, it won't fill a stadium or auditorium, but it could be used with a mic hung over it and run thru a P.A. because it gets some really good sounds with all the onboard amp modeling, effects, etc. For me, it's the practice amp that I've been trying to find for a couple years. Plus, with the battery powered capability, I can use it for several portable applications where AC power isn't available, even if it's just sitting out on my deck or patio. Plug an iPhone or .mp3 device in and learning songs becomes a breeze. Thanks to Jon Gillespie for hooking me up with this!
Music background: Been playing for 50 years at both the touring professional level as well as locally.

Does a great job!

We love it!

Great small bass amp

Fantastic amp for practice or acoustic campfire jams. Had so much more capability than I realized. Really like effects and drum machine built in. Then it runs on AA batteries!!!

Sweetwater Advice

Carson McClain

Technology is our friend and this amp proves it. I am just wondering if there is anything this can not do! The amp models sound great as do the FX, you can plug in an MP3 player to jam with, and you can even use the internal beats to practice your playing speed. A great amp for the apartment, or for the beginner.
