Ron worked with me on finding a weird jack for my Gibson Duo-medalist footswitch and made a switch that works for both reverb and tremolo. He sent the jack he suspected would fit and let me check if it was the correct one before we proceeded. Every other "custom footswitch" company that I contacted shot down my proposal as soon as they saw a picture of the strange 4-pronged jack. Ron somehow got his hands on one, build a really nice switch with it, was very friendly the whole time AND even gave me an extra plug to hold onto for the future. I couldn't recommend him any higher.
