OVERACHIEVER! Sounds great, works terrific
I acquired a Roland Mobile Cube a couple of weeks ago, as a gift for my son. He wanted a boom box to listen to CDs, mp3s, and streaming music, but since he is a bass player and could use a low-volume practice amp, I opted for the Mobile Cube. He loves it! Says it works amazingly well and allows him to bring his tunes wherever he wants to go. Score! THEN ... this past weekend I swiped it from him for use at an outdoor hippie festival. I spun the Mobile Cube onto a mic stand, plugged in a mic (xlr mic with an impedance matching transformer/converter to 1/4"), and an instrument cable, put in six new batteries, dialed in a bit of reverb, and let a whole series of performers use it over the course of an afternoon. This is the first year that the festival had any sound reinforcement at all, and the reaction was overwhelmingly positive. The Mobile Cube made it possible for a solo singer/guitarist to be easily heard much further away than usual. This allowed each performer to concentrate on sounding good -- rather than concentrating on singing and playing as loudly as possible -- and it allowed many dozens of people to enjoy the music rather than just those who were seated directly in front of the performer. I got many compliments and many reactions like "Wow, that thing rocks! I gotta get one of those for ..."
If I could make one wish for this thing, however, it would be that Roland would put an output on it, so these amps could be daisy chained or used as a proper personal monitor. But aside from that, it's totally awesome. (I'm probably going to buy another one so I don't have to keep borrowing the Boy's! I _know_ this thing is going to get used a LOT.)
