If you want a really small amp, and I mean REALLY small, then there’s a new kid on the block: The Boss Micro Cube Bass RX. The cube family has been around for as long as I can remember, but this new bass-version really has taken it to another level. Roland has posted a video that goes through the product details, but I’ll give you a run down on their new bass amp here:

• Stereo amplifiers, with and four 4-inch (10cm) speakers.
• Eight COSM® amps, six Boss digital effects.
• Rhythm Guide function for practical rhythm training.
• Stereo AUX input for CD/MP3 player, Phones/Recording out.
• Battery driven (6 x AA, up to 13-hour continuous use).
• Built-in carrying strap.

You’ll not be playing stadium gigs with this guy, but as a portable practice amp it ticks lots of boxes. It looks the part too.

The four mini-speakers are custom designed, and provide stereo sound (to go along with the FXs) – a fairly unusual feature in a bass amp, and one that you’ll either love or say “meh!” to. I’ve been a user of Roland’s COSM technology for many years (both in the GT6B and the V-Bass that I have as part of my own rig). It produces very convincing simulations of the major amps and is a useful creative tool. The COSM and effects features, combined with the stereo aux input makes this a great little practice device. It feels super-portable, and even has a collection of built-in drum grooves, although how useful they are in the long-term I’m not sure. Either way, it’s easy to plug in an MP3 player or computer and use backing tracks or drum software too. This diagram from the spec sheet gives a better idea of what it can do than me rambling on, so have a look and check out the Roland site.
