How come uprights, or for that matter, pretty much any acoustic instrument in the viol family, don't have volume and tone controls on their pickups a la electric guitars or basses? Is it simply a matter of not wanting to drill holes and having no place to put pots? Or is there another reason? I imagine people who don't double on electric wouldn't care so much, but I do. I would think that life would be so much simpler if you could just reach down and goose a knob on the bass when something is ka-flooey rather than have to make the change on the amp where it affects the electric, too. I guess you can buy a preamp and tape it to the tailpiece, but I think there could be something a little more simple and less obtrusive. I'm just curious as to why it's not done.
