Shiral,

The keyboards now have their separate inputs -- Tape 1 and Tape 2. I just don't want to take any risk of sending them to the repair shop. So they are happily playing along in their own realm right now. Of course, the down side to this is that I cannot be playing both boards at the same time, and have to lean over and press an extra button on the amp when switching is needed (as if I don't have enough to keep my hands busy.)Thank you for sounding the warning. I think it's time for a trip to GC to pick up a bargain-priced Behringer. A little money spent now may save a bunch later on. Thanks very much. I surely appreciate your input.
