In the spirit of “question everything” (Thanks Ron) we should see if the textbook setting of the jack is THE best way. On older parts I’ve had to align the jack/knuckle back a bit (note: only on specific notes) because the jacks would cheat, and on newer parts I’ve actually gone a bit forward to get the right feel. Maybe our “visually impaired” friends have it right…<o:p></o:p> <o:p> </o:p> I’m going to do some experimenting.<o:p></o:p> <o:p> </o:p> Regards,<o:p></o:p> Jim<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of David M.

However, have you tried the “feel” method Michael W. wrote about? I’ve used that method to check for cheating jacks, but have never set jack position with it. I’m wondering if this “feel” of the jack will be as accurate (or more) for touch as the sight method. Once again, asking a simple question like this has caused me to examine my own long-used techniques. His experience is more vast than mine so… I’m off to experiment! <o:p></o:p> <o:p> </o:p> Regards,<o:p></o:p> Jim Busby<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of Jon Page Sent: Monday, August 06, 2007 1:58 PM To: caut@ptg.org Subject: [CAUT] Black on Black...
