Topic: Goodrich VP Stiff - Help |

Last weekend during a show, my Goodrich VP suddenly got stiff right in the middle of the swing. I played the rest of the night either too loud or too low; i could not freely swing on the pedal.
The string looks fine; the problem seems further down, where the shaft goes across. Half-way through the swing, it starts to almost grind against something. I tried loosening the screw and adjusting that, but it made no difference. It is like it's hanging up on something, like rubbing against steel. Any ideas what could be wrong? Thanks. |

This may not be your problem, but I just replaced the pot in my Goodrich. It was grinding until I realized I slid the pulley too far down the shaft and it was rubbing on the mount. Possibly your pulley slipped. ??
Hope you figure it out.

| If it gets close like that it will cause the pot shaft to bind. Release the pulley, slide it back for some clearance and then tap on the shaft end to free it from the bind it is in. Done this one before!!! |

| I'm still not exactly sure how to execute what you're describing. I have an L10K, and I think the shaft and pot are installed a little differently than a standard 120. I'll see f I can get a pic up here later. |

| Hi Chris. Loosen the set screw on the collar of the pot and see if the problem goes away- if so- the problem is not in the chassis but the collar rubbing on the pot or the pot itself. If so- take off the string and the collar and rotate the pot to see what's happening. See you in Dallas? |

Hi Jim. I loosened the set screw, and yes, the problem is in the pot and not the chassis. The grinding is coming from the pot shaft. What should I do? Does this mean a bad pot? Maybe I can bring it to Dallas and get someone to look at it.
Yes, Jim, chocolate martinis all around next Friday night!  |

If loosening the collar and moving it farther from the body of the pot doesn't help (not much of a chance)- replace the pot. Do not mention Chocolate Martini's to me ever again- besides the fact that my lovely wife Karen will be joining me this time keeping me on the straight and narrow (more or less), that particular drink gives me purple haze  |

| Once the collar is away from the face of the pot you must strike it with something to release the pot shaft. It will bind up until it is released. |

| It has been my experience that, once there is a problem with a pot relative to binding, it is usually a waste of time to attempt to remedy it with other than a replacement. I frequently am able to restore old AB pots when they are scratchy but do not bother with those of other manufacturers as usually any gain is short lived. |

I brought the pedal to my tech, who has deemed the pot ready for the scrap heap. He explained some mumbo-jumbo to me, which is in line with what Jim has said about the pot being useless once this happens. Thanks all for your help. How about we stick to beer in Dallas, Jim?  |

If the pot-shaft has not locked-up, try loosening the screw on each side of the pedal that holds the top and bottom together. Also some good quality oil on those screws might help also! Don't loosen too much, but; just keep them snug!

| Apparently they make you hallucinate, at least that's what Jim told me in St. Louis. Check the flights, Mark! |
