As others have said, sad news.
John was an old school gentleman who knew the value of customer service and brand reputation.
I bought a single pickup model and after a very friendly conversation with John I sent it off to them for a pickup upgrade.
Even though they were really busy with customer builds John managed to squeeze in the pickup upgrade and the bass was back with me in good time.
I remember being surprised at the quality of the workmanship done in such a short time.
He belongs in the Bass Builders Hall of Fame.
A real loss.
