My Fender 400 intonates sharp after depressing a pedal. This happens whether the pedal raises or lowers the string. What causes this, and what's the remedy? |

Check to see if there's enough play in the cables.(adjust the turnbuckles if not)
Check to see if the pedals are not binding on their axles.(Remove, polish the bearing surfaces and lubricate with PTFE Based lube).
Check the rollers on the Nut are free..(Remove, polish the bearing surfaces and lubricate with PTFE Based lube)
Check the pulley system that the cables go around.(Remove, polish the bearing surfaces and lubricate with PTFE Based lube) _________________

Terje - are you saying it returns sharp no matter whether you engaged a raise or lower? If do - have you changed your string gage or brand recently, or made any other change in your setup?
Is it a new occurrence or has it always been like that?
FWIW It might take a few more details to figure it out.
Like Baz, my first guess is turnbuckles over-tightened, but some of the other variables need to be eliminated fort. _________________ No chops, but great tone

I recently changed tuning from C to A, and had to put on a much heavier set custom ordered from Scotty's. I had to re-tune the stop screws and used a tuner to get them just right. I did do some tightening of the cables, but cant tell exactly how tight they ought to be. Should they "hang" a little under the cabinet? If the guitar had this problem while tuned to C, it wasn't noticeable to me. And yes, it appears to return sharp whether I raise or lower. |

I'd try just a little "slack" in the cables by loosening the turnbuckles first. That's a common problem anda mistake I made myself early on. Give it a try and post the results - if that's not it (or makes some partial correction) then we're narrowing things down. _________________ No chops, but great tone

Terje, the simple answer is that the cables should be as tight as you can make them without moving the pulling fingers! (That's not very tight.) Tighten each turnbuckle until you can see the finger (the piece it's hooked to) start to move, and then back it off about a half-turn. With no pedals activated, all the raise and lower levers should be in a neat little straight line, and be pulled firmly against the stop-plate.
Raise fingers are pulled against the stop plate by the strings, and the lowering fingers are pulled against the stop-plate by the springs |

Thanks! Problem solved. Turns out the cables were too tight. While correcting this problem I found another. The black screw that should set the amount of lower on my second string is totally disengaged. I can turn it full travel from left all the way to tight, and it does not affect the string travel one bit. This string should lower from c# to B, but it goes a few cents too far. Any suggestions? |

So the first suggestion I made WAS the answer..

As for the disengaged screw..It's solvable. But I'm going to bed now and it's likely that when I awake, someone will have told you how, probably that Jim Sliff guy !! |
