Sour unison

[Joseph Alkana]

Yeah, that can be a head scratcher for a while too. But no, coil and becket were fine, although the pin was a little high for my taste.

  Becket slipping out of the pin? (Happened to me once ... just a real slooooow slipping of the coil, for several tightenings, then it let go altogether.)

    OK folks, anyone want to tackle a little fun mystery question? This one is probably directed at the newbie, as the seasoned veteran should pick up on the answer pretty quick...I think!

    Tuning a newer Kohler and Campbell SKG 600 (grand) that has individual tied strings. String near last plate strut in treble doesn't want to stay in tune while I'm tuning. 
    I checked the wire for possible trouble and couldn't see anything obvious, except the routing seemed a little crooked. So I straightened out the wire routing, seated sting  lightly on bridge, eased the rounded areas of the wire at the capo, and made sure the tail was seated at hitch pin. Pulled string to pitch and all seemed well. I congratulated myself and proceeded to make out a bill. While waiting I rechecked the note in question, and, the right string was back out of tune again. Ok, I said to myself, I must not have gotten nearly enough stretch out of the wire or something, so I whammed it into tune once again. Customer is now on phone call (don't you hate that when it happens as you're trying to get out the door?)

    Soooo, I'm sitting there playing on the piano and poke at the offending sour unison, just to make sure it was holding solid. Yikes! It was out again. Now I'm getting nervous as I am sure something is wrong. But what? 
    Any takers out there as to what I discovered?
