Pete Si, what does this wireless device do?

It's a wireless system that replaces the cable between the instrument and the amp/pedal board.  If you google the one mentioned in the post you can see and read all about it.

Bill, tgo

The one I mentioned, while not perfect, works well with Alembic basses. The other brand I found that works well, and I feel is a better product is the set from kliq. I've tried just about all the other brands and these two are the only ones I've found that I didn't have to return. The real negative with these things is battery life. They're all terrible.
