I have a Derby S-10 guitar that I bought new about a year ago. I am having having problems tuning the knee lever that lowers the E strings to D#. When I turn the hex nuts they lower close to D#, but then stop short of getting to D#.
I am a relative beginner. I have been playing about two years and I know very little about the mechanics of the guitar. |

Joe - It sounds like you will need to either adjust your knee lever stop to allow a bit more movement, or move the rod to a hole in the bellcrank that is further from the cross shaft. It is probably easiest (and best) to adjust the stop - it is probably just a set screw. When you look under the guitar and move the lever, you will see some adjuster that limits the travel of the lever. Just give it a tiny turn in the direction that will allow the lever move a little further - then adjust any nylon tuners that are on the lever.
Good Luck!
Tim

Derby uses a second row of screws at the end of the neck above the nylon tuners. These are used for split tunings and they are the "boss" of the lowers. Check that the split tuning screw has enough slack to allow the changer to lower to the desired note.
Add a little extra travel then adjust the final note with the nylon tuners. |

Posted 28 Apr 2009 9:05 am Few questions?
|

1. Did it tune correctly when you bought the steel?
2. Are you using the same string gages it came with it originally?
3. Have you made any adjustments other then at the tuning key or nylon nut?
4. Does your Derby have splits on all strings? (A metal hex nut that adjusts the lowest stop or note on that string)
I suspect it is an adjustment and an easy fix. You can email me if you would like. Derbys are fine instruments, I love mine. |

| Joe...On the end of the changer housing (behind where the strings attach) you will notice a series of allen head set screws. Engage your knee lever while at the same time check to see if the finger is touching the corresponding screw(s) before the string reaches the desired pitch. If that is the case, simply back off the problem set screw to allow the finger more travel. Hope this information proves helpful....My apologies to Jerry, he posted a similar solution while I was still typing mine, (always nice to have my opinion verified however.) |

What was recommended above is on target, however; before you make any other adjustments; check to make sure that you have a tiny bit of KL-movement before the change starts. If you have no extra pre-change travel, check the L-Bracket that is attached to the KL and the Center~Brace. Looking straight down, you'll see a tiny allen-screw. Turn this small allen-screw about 3/4-turn counter-clockwise and that will give you more Lever~Travel and also check to make sure that all the unused split-tuner screws have about 1/2 of their heads sticking out of the end of the neck. All strings that lower run through the changer-hole fartherest from the top of the body.

That's about the best and easiest solution! It's very unlikely, since you are the original owner; that the tiny allen-screw that I mentioned would have gotten out of proper adjustment, since Charles adjusted that when the guitar was assembled. As long as you are the owner, none of the allen-screws under the guitar should ever need adjustment, unless maybe when you change the copedent at one time or another or want to adjust the spacing between KL's! That split/tuner screw adjustment is probably the solution to your problem!
