Topic: A Pedal moves when depressing C Pedal |

I've got a Mullen G2, SD-10.
When I depress my C Pedal, the A pedal moves as well.
It's strange, when I turn the guitar upside down this doesn't happen, only when the legs are on the floor. Thought maybe the pedal board needed to be tightened but that didn't seem to be the case.
I was thinking at first the 2 rods attached to the 5th string raise were rubbing, but I'm not so sure that causing it. What I found is, if I apply more tension to the A pedal - by raising string 10 an extra half step to D, the A pedal stays put.( This was just for experimenting. ) It seems the extra pull required by the C pedal to pull the 4th and 5th string a whole tone, is causing the A Pedal to go along for the ride. I'm pretty sure the rods are in the same holes as when I got the guitar, so I haven't changed anything. I don't notice it's affecting the tuning any, but I gotta think the extra energy required for the C pedal to also impact the A Pedal, would make the C Pedal harder to depress. Appreciate any Ideas you might have. Thanks. |

This will happen on a lot of steels, and it's really not a problem if it doesn't affect the tuning or playability. Usually the (untouched pedal) movement is small, and doesn't add to pedal tension of the pedal being used because it's actually caused by releasing tension in the pulling train. Knee levers will do the same thing, sometimes.  |

Your 10th string pull rod should hold the position of your A pedal and it should have only a small amount of slack if timed properly with the 5th string A pedal pull.

They are attached to the same pull so when one pulls it releases the other. This allows gravity to affect the pedal downward in a ratio related directly to the travel of the released minus the allowed travel of other attached rods. If you have a lot of travel on your 10th string A pedal you may have noticeable pedal drop.
Sometimes the released rod will actually bind due to the angle change of the hole the rod travels through causing the rod to bind and be pushed, pushing the pedal down.
When you turn the Steel upside down the pedals drop to the stop which is the max the pedal can travel in that direction.
The gravity affecting the pedal when the steel is upside down is usually enough to override binding if there is any.
Therefore you will generally not notice any movement in the pedal when you engage the C pedal while the steel is upside down. |

| Stuart, thanks for the explanation. I couldn't figure out why when I flipped the guitar over the problem disappeared. |
