I am getting closer to having a working solid-state overdrive control. In this video, I demonstrate the printed circuit version on my bench. The next step is installing in my TR4A. I am interested in located 2-3 people who have A-type overdrives who would be able to install and test my control. The cost to the testers would be very minimal, just covering my costs to build these first units. The testers would have to be located somewhere that allows them to be able to drive them year--around.
If you are interested, send an email to [email protected] with the subject "Overdrive Control Tester".
Thanks,
Dave
