Brassbandmajor: no. Gordon came up with his design on his own, and as the universe sometimes works... I had a similar valve-set already made for a flugelhorn. Somewhat Kuhlo inspired... but not. For many reasons, none of which I will go into here.
"I myself don't use any triggers. I set and forget. I don't use water keys, and I use as little as I can get away with as possible. Chase the dream Gordon!"
As little as possible....
You know, one of my favorite guitar builders lives about 30 miles from me. Rough as a cob...both he and his works. His shop burnt down about a month back, destroying all his equipment, jigs (such as he had), his wood, and several dozen of his guitars.
His builds were never considered "journeyman" but rather more often referred to as "mountain craft"...
His guitars were neither fancy nor even symmetrical...each was made in a rather rough fashion. No jigs...freeform. Not really even much in the way of plans...no templates.
But they each had personality..
and they worked.
His was minimalist stuff, no marquetry, no bindings, no fancy woodwork.
Alternative materials were used as he found reasonable and local.
Offcast scraps of acrylic marble countertops were cut into bridges with integral saddles.
Piano soundboards were planed and repurposed.
A tree fell in his back yard, or down the street...it was sawn for timber and left to dry.
His only recent concession to expediency was to lately buy precut fingerboards, already slotted...and that was reluctantly done in his old age.
His guitars just worked.
And they were different from anyone else's or even his own.
I loved them.
I just stopped in one day unannounced, and he stopped his work on the most outrageous RATROD lowrider truck you could find to take me through his whole process of building guitars, his history (Gruhn's Nashville), his tools, his philosophy, his life, his wife, his instruments, his raw materials...
He shared EVERYTHING with me.
He was the ghost of every '60's hippie past, still looking and living the part, in his own way and at his pace.
George Wishnevsky. Wishbone Bass guitars and pretty much everything else. Winston-Salem, North Carolina.
May he restart his backyard business...with as little as possible.
