An old joke comes to mind. "How many guitar players does it take to change a light bulb?"
While I'm here.....
I clip each string just exactly center of the end of the fret board and where the string rests on the saddle. So yes each cut will follow the contour of the intonation. The real magic comes from a handcrafted wire cutter hand made from hand forged hand picked #666 steel. I found a monk in Tibet who uses an ancient scroll to summon this rare gauge metal straight from the depths of hell (or so he claims).
I find that snapping the strings in such a manner jostles the moleculer structure of the wood and really opens up the tone. And only, I do mean ONLY, do those snips cut the string fast enough to release every ounce of the string's tension to give it the whiplash effect strong enough to open the neck's true tonal potential. It really does work. Really. My dog howls after every string change. And you know dogs can hear things humans can't. Really, they can.
You guys can see the rest of my stringing techniques in this months "Stringer's Digest". :lol
