Never having played upright my only exposure to the instrument is as a listener and the occasional plucking of my son's school bass. The action on my son's bass would probably have James Jamerson muttering about hand cramps. I realize that there is some trade off between volume and playability but it would seem that with good amplification and pickups the former would be a distant second consideration. I'm curious how low the action on an upright can be set and what are the considerations in doing so? How is your URB set up?
