I have a 1937 Kay that I recently purchased and sent it in to a good luthier in Nashville. Among other things, he planed the fingerboard. Straight as an arrow, no scoop. His opinion is that no scoop is needed on an upright. I have since learned that most basses have "the scoop". Plus now there is some moderate buzz up and down the neck. (gut strings, bluegrass bass). Somewhat annoying but livable. Is there such a thing as a very flat planed fingerboard being considered "proper" setup for an upright bass?
