Wiardgroup

By pricing such a quality product where its at you have created 
this "problem".  In order to get a comparable Serge system with the 
functionality of a 6 unit Wiard panel one would need to spend on the 
order of 8000.  The Wiard would be almost half that.  

Your margins are so low you are really like Santa Claus gifting Wiard 
to musicians around the world.  This is a noble approach but there 
are more efficient ways to make charitable contributions to the 
struggling musicians of the world.

Honestly Grant the solution to your stress is raise your prices.   
Raise them high enough that demand drops to a level you can 
personally handle and/or you can use the additional revenue to hire 
outside help to stuff the boards for you.  You would still be able to 
put out your lovingly handcrafted instruments.  People would still be 
thrilled to use them.  They wouldn't turn into museam pieces. This 
doesn't turn you into Roland churning out plastic XoX replica 
boxes.   

It is often the case that artists are so happy that people appreciate 
the beautiful creations that they don't price their time enough in a 
misguided effort to get their works out into the world.  Grant, the 
musical community loves your stuff.  Let them compensate you 
appropriately for putting so much of yourself into your instruments.

You are worth it.
