A Dampp Chaser system was installed at the time of the rebuild. About 6 months ago the owner noticed about one octave of sluggish notes. He called another technician who came out and lubricated the jack flanges. It didn't help and more notes started getting sluggish. He called the other tech back, who lubricated again. The owner said after the second round of lubricating the problem was even worse. I don't know what the other tech used to lubricate, but I'm assuming it was Protec. I gave the owner a quote for re-pinning the jack flanges. But two questions linger. If I re-pin, will the problem re-occur; and why did this happen in the first place. </tt></pre><pre><tt>Greetings, </tt></pre><pre><tt> Renner pinning does this.
