Session Orchestra S

The Orchestra S will from now on have a valve on hole 2 blow. This improves the airstream a lot . In the original design hole 2 caused some problems and this is solved with the placement of a valve.
Please feel free to contact me if you already have one without the valve. You can send the harp to me and I'll put the valve in for free.
