  Carl, 


  Are you wanting pictures of Pitchlocks on the front duplex?


  If so, the Pitchlock.com website has them.

      The first thing that comes to my mind is will another technician realize the Pitchlocks are there? It's fine as long as you're the only one tuning it, but someone else might not notice them at first. 


      What about putting them close to the agraffe so they're more visible?


      I've had good results with using Pitchlocks on some Steinways with lots of front duplex noises. (On Steinway D's the C6-E6 area can be pretty awful.) And have used them on bass bichords a time or two.

        I finally have come face-to-face with what has been written about for years..
        An "icky" Yamaha GH1, with the untunable group of plain wire notes in
        the lower tenor section.  I know I've tuned a couple of GH1's in the past,
        but none were this terrible at the break.  B is the lowest plain wire, and from
        there up to about Eb, they couldn't ever sound decent with the octave above.

        I realize that there are better, more permanent, costly options, but I wanted to give
        this a try for a church where I rehearse with a men's chorus...

        I pulled out my little canister of pitch lock clips and went to work on the 
        bridge side of the strings - closer to the bridge has a minimal effect, while
        further into the speaking length has a more dramatic effect.  The unison can
        be "tuned" by moving the clips - the further from the bridge, the flatter the 
        pitch.

        It is really, "less bad" than before.  The downside is that the only way to 
        tune those strings now is with all three sounding - a nightmare! That, or maybe
        sliding the pitch locks up and down.  I'll be experimenting as the weather changes...
