i remember a few months ago someone was mentioning how it would be possible to make an electric whistle… i want one… you could make it quieter for practicing.. maybe even plug in headphones? easy to record yourself, everybody on the board could listen to each other play;) I wonder how much it would cost to make a prototype…?
Fairly cheap…
The last one I say was only the price of a walton’s whistle.
Plus ~$2000 for electronics…
