I service an older C7 that rendered poorly, especially raising <g class="gr_ gr_36 gr-alert gr_gramm gr_hide gr_disable_anim_appear Grammar" id="36" data-gr-id="36">pitch</g>. I discovered that the bulk of the friction was coming from the string underlayment felt between the tuning pin and the agraffe, even though the angle down from horizontal is small.
Liberal applications to the felt of CLP for center pins improved it tremendously, to my pleasant surprise.
I've used a variety of silicon bicycle chain lubes for the capo bar. You can always drop pitch, move the strings sideways, and remove any grooves from the underside of the capo bar as well.

Hi folks,
Lately I've come across pianos that have pretty awful rendering while tuning. I'd like to know how some of you handle applying Protek (or some other preferred material) to the string contact points like the agraffes and capo bar.
Thanks,
Happy Tuning!
