Runoffgroove "Big Grace"

Big Daddy and Grace circuits have this at the end of their document page: The two circuits are very similar and it may be possible to use a switching system to alternate between the buffer and the gain stage versions. (ROG)

Now did i really have a choice? :) Instead of using some monstrous 4PDT switch, i thought it would be just easier to accomodate both, the JFET buffer and JFET gain stages, on the same board and use 2PDT switch to switch between them. Takes more components, but i think you can build three of these circuits for the price of a single four poled switch.. So. I dubbed it, the "Big Grace".

Demo of his build by Madferret.  Thanks mate :o)
