It arrived yesterday. I plugged it into a USB charger, turned it on and tried it with headphones and a mic at the house. Looks great and the preset reverb sounds really good too. I tried it with a condenser mic too. I will take it to the job tonight and give it the real audition.
In order to change the effects, compressor, or e.q. settings, you have to use a program, which you download for free, from the computer. This is to save space I suppose. Seems simple enough to do, but that doesn't affect me because I use all that stuff from the keyboard anyway.
It SEEMS ideal for my need. Stay tuned!
