Its a great little box I feel is overlooked because its not considered TOTL. I think for most players its all you need but that will get me killed on this forum HA!
For example:
Saw a great , and I mean a very, very entertaining tight group on our trip to South Carolina last week. All older (at least 60) three piece. Bass, Guitar, Female on Keys (used sparingly ) and a very simple drum machine. I couldn't see what it was but all they did was kick in a basic beat in and do a bunch of dance tunes over it. All sang lead and did some nice harmonies. Only once did I detect a bit of a sequence for a Lady Antebelum tune. Three hour gig, no breaks, and the dance floor was never empty.
Made me stop and appreciate what a lot of talent and a little bit of technology can do.
Also talked to a bar/restaurant owner who hired a two piece and when they came in and just sang over Mp3's he let them finish the night and told them he'd never have them back. Gotta love it !!!!
