Roger, the original post (more than 6 years old) asks on which knee people put their E-lower, and the poll gives 4 options, not 2.The essence of this poll is to see how many move their Es with their right knees, surely?
If that's the case, then both Emmons and Day players (I'm 'Day') who raise and lower the Es with their left knee should be added together.
I imagine that many if not most who put it on LKL set up Day. But I have seen Emmons setup guitars with it on LKL - never undrstood why, but I have seen it, as well as people who post setups that way.
Then there are various rationales for using one or another right knee lever for the E-lower.
Another relevant issue with this is whether or not one sets up E-lower and E-raise on the same knee or on opposite knees.
So no - I don't think the only issue is whether or not people set up the E-lower on the left knee or right knee.
I don't know if the poll is still running, but even looking at it as a Right-Knee vs. Left-Knee discussion, the percentages of people who responded are about 56% Left to 44% Right, which is actually less of a Left-Knee majority than I expected. And of people who responded since this topic got resurrected, it's 13-5 "preference" for Right vs. Left. Not saying that is statistically significant in any way, but interesting.
