The final version of my interchangeable Tone Bar system is ready, but for now I can only show you a few prototypes from its development. After testing many materials, I chose carbon fiber reinforced PA12 for the final parts. The locking system still works perfectly after 5,000 insertion and removal cycles. Three pogo pins connect the output jack and piezo inside the Tone Bar to the electronic controls mounted on the pickguard. The custom carbon components are precision calibrated, allowing the Tone Bar to slide smoothly into the guitar body.
