I did a Christmas special with my band Monday with my Hammond SK1 and SD40 module; great sound. Wed is my Karaoke show with 90% Christmas, with my church dinner immediately following with 200 in attendance, using the same rig. Thurs was an assisted living gig with virtually no room to set up so I did the show with just my SD40. I used midis and CDG vocals for a lively hour. They loved it. Christmas day is the big Christmas dinner at our Cultural Center using the same SK1 and SD40. It is a real killer combo.
