Is your design proprietary? I'm looking to build a high impedence input FET preamp feeding a mono headphone amp that I also need to build. I need these for my new Godin nylon string Multiac. The lazyman's option is to buy a Ultrasound AG-30 amp.

I'd be interested in comparing your preamp design to the Tillman circuit too if you're up for sharing!
