Feature:
The effects are ok, but naturally a little limited. There's no possibility to change during the rehearsal the amp type and the effects of the same category (flanger, chorus, t-wah and delay reverb). The absence of a line out is the great deception in this model. It would perfect to take the amp modelling and effects in a bigger sound system.

Quality:
Roland... no further comments. Build like a fortress. Rettain the brand new aspect during years.

Value:
It is the expensive model in the category (30 W practice amps), but you really have what you pay.

Desirability:
Again, in these category, believe me, you will not want any other, if you try it.

Sound:
In this category (practice amps), there's no concurrent! The sound is clear and incredible strong from such of little combo. The COSM amp modelling make it sounds perfect for every music style. Really cool...

Support:
I'd not deal with it. Some friends that needs Roland support says that is perfect.

Overall:
Perfect for my needs (practice and little rehearsals). But now I'm looking with desiring eyes to Roland 100 bass. More power, line out, DI, external speaker... Oh my God!!! We never stop to spend money with these delicious toys!
