The Tillman jfet booster circuit is widely known in the DiY effects community and often recommended for certain guitar fx applications. I recently saw the circuit posted on a guitar forum and realized that it could be built on my Multi-Purpose pc board.
I’ve modified the instruction page for the pcb to show how to use it to build the Tillman. The instructions and parts list are on the site that is emailed to everyone that buys one of the boards. Ordering info:
