Roland Micro Cube Bass RX

Been using this for years, mainly for busking or as my speaker system for at home (I don't own bluetooth speakers yet, so it's a cool alternative).

The casing is very sturdy, these amps can be battered, abused, thrown down staircases and whatnot.
I've never been a big fan of COSM-technology (the amp sim models), it sounds really digital, but you do get a nice variety of tones of that doesn't bother you. The effects sound really digital as well and often take away quite a bit of low end.
However, the seperate aux input bypasses all that and if you play a backing track through it, it sounds really good through the 4-way speaker system.

It's not really loud, so if you're busking near busy traffic or with say a cajon player, you'll get drown out easily. Most basses will distort at even medium volume, and it's not suited to amplify double basses. Of course with such tiny speakers, that's to be expected
It's not very heavy but not exactly light weight either, so to lug it around on the street I would advise a trolley.

If you don't use the effects, on a battery brick like the Volto, you can actually play for practically the whole day, so the power drain is reasonable.
It has a built-in metronome, but it's not very practical. Nevertheless I often use it as a practice amp.

- The COSM amp sim models don't cut it
- Sounds on the wrong side of digital
- the FX take away low end and sound cheap
- Doesn't handle a high input level graciously; distorts easily.
- Hard to cut through background and traffic noise, though it's meant to be an amp for buskers
- The metronome is unpractical
- The tuner is cumbersome and the compressor useless
