I've had the good fortune to spend many pleasant occasions visiting with John and Lin at Winfield. I'll look forward to seeing Lin again, but of course will miss John.
One thing that sticks in my mind is the double bass he designed and played. Double washtub bass, that is. It had two washtubs joined at their open ends, making a resonating chamber with twice the volume of the typical washtub bass -- clever concept and clever name. Unsurprisingly, the rest of its details were superior to those on the average washtub bass as well. Product of a brilliant and slightly (though delightfully) kooky mind.
I'll cherish my memories of him.
