i think Drakulie is assuming the clamp is farther than as close as possible like maybe two inches on one string when the clamps are close together. Of course if you clamp the string as far from the tension head as possible it would make a big difference. I assumed Tennusdude was talking about very small differences. There is a difference but very small if done correctly.
I have the ability to drive people crazy, not sure if I was born with it or I learned it but I'm damn good at it.
