Roland Micro Cube Guitar Amps: Review

The Roland MICRO CUBE (MC) is the most popular battery-powered amp of all time, and has been around for more than a decade. Over the years, the MICRO CUBE has retained its compact size, but it still remains a powerhouse (thanks to its legendary predecessor), and along the way haave added several new features to stay in tune with the times.

Available in RX and GX models.

While most experienced guitar players use a bigger and powerful guitar amp for their gigs (for example a 65 watt Marshall for most things), they can be really heavy to lug around, that is why they also own a practice amp that is easier to carry anywhere.

The microcube amps are smaller, sound sweeter, and is an excellent amp for practicing and training (you can play Jimmy Page, Jimi Hendrix or Metallica styles just by switching buttons), has enough distortion for almost anything, has great fx too. 

The amps may distort a bit with the volume cranked up, but for certain settings, it stays clean and can get really loud.

Its easier to set up as well, compared to your real rig; at times you just want something that can be set up quickly (especially after your 12 hour shift).

This is one of the best sounding Solid state amps.

Roland Micro Cube Guitar Amps: Pros & Cons

PROS (for both the models): Weighs only a few pounds. Size of a car battery. Runs on batteries. High Quality effects.

The recent MC amps come with robust jacks (this is usually a major weak link since you are constantly plugging in). Runs on AC power (included) as well as on batteries. A carry strap is provided to make it easier to carry.

These sound impressive and have lots of power. The look cute, but at the same time are ruggedly built. The biggest plus, as per most guitar players, is that you can take it outside and play it (without needing power supply); the battery setup is really cool. You can use it with your lead guitar or even your bass guitar. You may also plug in your microphone in for some fun.

For the more experienced guitar players, this can serve as a handy second guitar amp; you can practice at home without shaking the whole house. Believe me, its difficult to find something that is small that still sounds good. People around you will be amazed to see that such a small thing can produce such a powerful sound. In addition, it has cool features like built in tuner, drum machine, and more.

Roland Micro Cube: Best Battery Powered Guitar Amp

Its definitely among the better battery powered guitar amps out there. You can take it anywhere you like, be it for practice or for a quick jam session (take it to the park or for small gatherings without the need for AC). You just can’t do it with a large combo or cab stack (it doesn’t make sense).

These amps do come with an AC power adapter, so you really don’t have to burn the batteries, unless that’s the only option you’re left with.

Roland Micro Cube: Small is Beautiful

The best thing about this guitar amp is that its small in size. It may look like a toy from a distance, but when you pick it up, you will realize that its no toy.

And in terms of volume, its all you need for solo practice. You can practice at home without shaking the whole house. And as most experienced guitarists would agree, its difficult to find something that is small that still sounds good.

Keep it anywhere at home – in the book storage area, near the sofa, or in your bedroom. Just power it up any time you want to play your guitar (its quick to setup).

Mind you, its not a gigging amp (even though you can crank up the volume). It isn’t powerful enough to compete with electric guitar’s volume in an outdoor setting (you could mike it into a big amp or PA for bigger sounds). If you need more volume (or don’t want a battery operated amp), checkout the more powerful guitar amps from Roland, Hartke or Behringer that will give you more power for your bucks.

But keep the volume at reasonable levels and you will love it. Besides, these offer good mobility. Roland MC amps are excellent for practice.

    If you want a small amp for your guitar that takes up very little space and offers a variety of sounds, this is a great amp to have. I own other higher quality/large amps also, but this one is too easy to plug in…no messing with pedals, cables, etc. The quality of the effects is very good, though some are not relevant. You can use it in a coffeehouse or small jam sessions or for practice. Effects range from acoustic tones (from my GR-55) to screaming Metal tones. It is surprisingly loud for its small size. I would definitely recommend this to any beginner or even an experienced guitarist (as a second or practice amp).

    The mid/treble range sounds a bit brighter than the bass (for those bass guitarists). What works in its favor is – portability, tonal options, quality.

    The Microcube is definitely among the best battery powered amps that you can find in the market. Just check the musicians playing on the streets in New York and you will find most of them playing through a Roland MC. Various amp types/presets, different effects (distortion, modulation, reverb, delay), its a must for any street performer. Battery power means you don’t have to be stuck to an electrical outlet. Runs on AAA batteries. You can also link to iOS devices (iPhone, iPad), you can get even more creative. So hit the streets, show off your skills and earn some tips.

    It has some cute features, the 4×2.5 makes it louder than it really is, but it is just a practice amp after all. You could look at other cheaper options (20 watt Behringer) for a practice amp with a volume and some EQ. You don’t really need that much amp modelling. You are paying for the effects and the emulated sounds, which will be seldom used.
