Hi Richard,
I have a keyboard stand that I have used for a long time - to stand while playing my dulcimers.
At first - I used 2 pieces of shelving covered with the rubber shelf liner.
The shelving was heavy, so I found some much lighter paneling and covered it with the shelf liner.
Once you have your "base" just adjust to the height that you are comfortable with, and Voila!
Works like a charm!
Keep strumming and smiling!
Cindy
