Let's see if I can describe... My A pedal tunes up fine when fully depressed, but the two strings it pulls change pitch at different rates... It sounds and feels like a very soft half-stop sometimes. How do I adjust? |

the only steel I ever owned that would start & stop at exactly the same time was the Kline Keyless guitar, most others won't do this, except maybe the old ZBs that I know of.Ernie http://www.hereintown.net/~shobud75/stock.htm ------------------

What steel is it? Some steels are easier to time the pulls than others. If it has round crossrods, instead of the more usual square, you're in with a chance. |

Assuming it's an all-pull steel...Timing involves the whole sequence of: Pedal rod pulling on it's cross shaft crank to cause cross shaft rotation. Cross Shaft rotating the pull rod bell cranks. Pull rod Bell Cranks pulling on Pull Rods Pull Rod nuts (at the other end) contacting & engaging fingers and pulling the fingers back. You've probably got a pull rod nut out of it's opitimal position at the end of the pull rod to contact the finger on either 5 or 10. Maybe the two are contacting their fingers out of sync. (see if one of the nuts is sloppy and away from the finger when all pedals are off) Could be as easy as syncronizing the nuts, or maybe changing the bell crank hole for pull rod on string 5 or 10. (Took me a while to figure this out with my Dekley several years ago). Ain't these machines fun...

Hey guys - thanks. It's a Mullen RP, yep, all-pull of course. Mechanically, it's great. I added a 4th pedal recently, though, so some re-rodding was necessary to make space for the Franklin pull on String 5, in particular. I got a rodding chart from Mullen, which served me very well. I'm just tweaking. |

It always seemed to me that it would be more important to get the various pulls of the pedal combinations (A+B, B+C, A+F, etc.) synchronized rather than the two or three strings that one pedal activates...But then again, I can't play like most of you anyway... ------------------ |

Good point, Mark... But if I can't trust myself with one pedal, how can I trust myself with 2? I'm starting small... haAnd thanks, Ray -- I ran home at lunch, backed off the nylon nuts, reset them to more equal position on the finger, and that helped a lot. It was pretty minor, just bothersome. |

Nathan, The later Emmons all pull guitars have 14 hole pulling fingers. These allow a person the time out all the pulls. I though this was an outstanding idea and machined out some for all three of my Sho-Buds. I've been able to sync up all the multiple pulls on my guitars. I sure you will have the same success with the later legrandes. You can view my Professional below. Leon

Put the rod connected to the bigger ga. string farther away from the crossshaft. If that doesn't do it, put the rod for the big string closer to the changer in the finger. You might have to switch some rods to do it, but you can get pretty close, even on a Starter. |

I agree Charlie, "close enough" is good enough for me! Personally, I think 14-hole bellcranks are plain overkill...kinda like having a tire pressure guage calibrated in 10ths of a pound. ![](http://steelguitarforum.com/rolleyes.gif) My own advice would be to worry about something that's more important, like just just learning to play the durn thing! |

Dang, Donny You and I are agreeing TOO OFTEN for comfort these days. ![](http://steelguitarforum.com/smile.gif) I went the other way. My Bud had 5 position bellcranks and, against my better judgment, I let Coop put the traditional Sho-Bud 2 hole pullers on my guitar when he rebuilt it. My 12 string tuning includes three B's to C# and three G#'s to A and he timed them out pretty close -- certainly close enough for me. I didn't think it was possible, but it feels just fine. I agreee that the 14 hole pullers are overkill but that is a beautiful guitar Leon has built and I sure admire his work. If you're really picky about getting the timing perfect, it's one solution. ------------------ Larry Bell - email: larry@larrybell.org - gigs - Home Page 2003 Fessenden S/D-12 8x8, 1969 Emmons S/D-12 6x6, 1984 Sho-Bud S/D-12 7x6, 1971 Dobro, Standel and Peavey Amps

Guys, the rodding was never really the problem. I think it was my hasty attachment of the nylon nuts after the pedal 4 installation - who isn't eager to try a new copedent? -that caused the problem. |

Leon - the undercarriage of your professional looks great but how do you raise the same string multiple times (ie- #4 and #5 on the E9th neck) with a changer that only accomodates a single raise using your bellcranks?[This message was edited by Jim Palenscar on 09 December 2005 at 10:25 PM.] |

Jim, thanks for the nice compliment. To answer your question, I converted my Professional over to triple raise/ double lower changers. The raise and lowering bars are stock later Sho-Bud parts. The top part of the changers were machined from 6061 aluminum by Albert Johnson. There is some modification required to the end plate and changer mounting plate. I will post a photo of the changer below. A little overkill never killed anyone. Leon

Thanks, Lee - I think I have it pretty under control now. The heart of the problem was that I just didn't spend enough time fine-tuning after adding pedal 4...Anxious novice just wanting to noodle, ya know?

To Donny and Larry, Just where do you draw the line between perfection and overkill? Is it overkill to try to obtain the touch and tone of Buddy Emmons when the majority of the listening audience wouldn’t know the difference between Buddy and the average weekend steel player? I have admitted before to being something of a loose cannon on the gun deck of steel guitar. However, when I come up with an idea to improve my Sho-Buds, I seek the council of Albert Johnson. He thought the 14 whole pulling fingers would be an improvement to the single raise, single lower pulling fingers of the stock Sho-Buds. I won’t even mention the 5 whole fingers on the later Sho-Buds. When the young man asked his question about syncing up his “A” pedal, I wasn’t trying to sell him anything at all. I was trying to tell him how I overcame the problem he had and what lead me to the course of action I took. I can’t stand the feeling of pulls actuating at different times. If it doesn’t bother you, you are truly blessed. I surmise that one man’s perfection is another man’s over kill. I can live with that. Leon

I find unmatched pulls to be irritating. If you're doing octave raises, or such, you get all this disharmonic crap going on until the pedal bottoms out.Basic principle of matching the pulls is to make sure they start at the same time, and then adjusting the relative amount of pull "displacement" (via the crank hole position) so they both hit pitch when the pedal bottoms. I think the displacement on the wound strings are related to the gauge of the core wire vs. the gauge of the plain (non-wound) string you are comparing to. I think the relative [This message was edited by Tom Gorr on 10 December 2005 at 10:19 PM.] |

I don't. I try not to obsess about anything. All I'm trying to do is help those who may be new at this learn where to concentrate their efforts to get the best return. I'd never tell Buddy or Lloyd what to use, they know what works for them. On the other hand, you don't see either one of them posting here on the Forum telling everyone else what they should or should not use! I'll never be a Buddy or a Lloyd, but like them, I've been doing this long enough to seperate the wheat from the chaff. Look at it this way, we've got players here constantly saying "tube amps are the only way to get a good sound". And yet probably 90% of the professionals out there use solid-state amps. We've got players here constantly saying "nothing sounds as good as a push-pull". And yet probably 90% of the professional players out there are using something else. We've got players here saying such-and-such is the best pickup, pedal, or amp, etc.. And yet probably 90% of the players out there don't use these. Now, we've got players here saying you need 14-hole bell cranks so you can get the timing perfect. If I'm not mistaken, the majority of guitars in use don't have 14-hole bell cranks, and most of the players that don't have them seem to be doing just fine. Do you see what I'm getting at? I don't have a problem with anyone wanting or using anything. It's when they start telling others that need such-and-such to sound good that I usually step in and say..."Wait a minute, 90% of the players out there seem to do just fine without that "thing" you're talking about." I think that clears up where I'm coming from. |

Leon, I like the pictures of the 14 hole bellcranks on your Sho~Bud. I have a couple of Emmons LeGrande II's and I really appreciate the 14 hole bellcranks for the very same reason you stated. ![](http://steelguitarforum.com/biggrin.gif) Erv |

Leon, Please don't misunderstand me. I admire your work greatly and said so on my last post. All I said was that my Sho-Bud has 2 hole pullers and John did a great job of timing the pulls with only two holes. The rods don't have to be bent and there's no clip to hold it in place -- that's a plus for me. My Fessenden has 5 position pullers and I've always been able to get pulls timed to my satisfaction. If I don't notice a problem while playing THERE IS NO PROBLEM for me.Donny and I are on the same page here. A guitar that pulls and returns accurately with good feel is all I NEED. Part of that is avoiding a 'hitch' in the pull where one string has begun pulling and another kicks in. I hate that too and will adjust it myself until it's acceptable. I still feel that 14 positions on a bellcrank is overkill but that's just my opinion. I can tell in 5 seconds after playing a guitar whether it is set up properly and all I know is that many of those that feel great to me DON'T have 14 position bellcranks. To me, that means they aren't necessary -- FOR ME. Please don't take this the wrong way -- I know you are a master craftsman and respect your work greatly. Merry Christmas. ![](http://steelguitarforum.com/smile.gif) ------------------ Larry Bell - email: larry@larrybell.org - gigs - Home Page 2003 Fessenden S/D-12 8x8, 1969 Emmons S/D-12 6x6, 1984 Sho-Bud S/D-12 7x6, 1971 Dobro, Standel and Peavey Amps

To Donnie and Larry, You were much more diplomatic in your rebutal that I. Please accept my heartfelt apology. My problem is, I enjoy working on a steel as much as playing one. You both provide some important information to the new players on the Forum. Keep up the good work and Merry Christmas. Leon |

Leon, Donny, Larry, and Co. - thank you for all the great insight. I didn't mean for anyone to get hot under the collar, but sometimes a little spirit brings more info to the table. : )Interesting sidenote: my Mullen came with an LKV that was machined and installed by the first owner -- but the parts are not modeled after Mullen parts. The bell cranks are 7-hole, and the cross shaft is round. Despite not being original, it has always pulled very smoothly and stayed in tune great. I never knew it until now, but I guess my steel is a "mini case study" in shaft and bell crank philosophies. |

keep in mind that balancing the pulls is equally important on the other end..you know, the changer end....using the appropriate raise or lower slot is part of the physics.[This message was edited by Tony Prior on 11 December 2005 at 01:59 PM.]

Leon and Nathan:There's nothing wrong with being passionate about what you do. Apologies are not necessary! The debating we do here teaches us about both the instrument, and about each other. I like to feel that we can disagree without becoming enemies, and that we're all here to help each other. |
