I have started a new thread about my problem with 3rd string breakage on my Excel Superb. If you have not seen the other post my 3rd string keep snapping after only a few hours of playing, I have tried all the usual stuff, different strings, removal of sharp edges, correct fitting etc.
The only other thing I can think of is that the anti cabinet drop tuners are not adjusted correctly and are adding extra tension. I have seen the manual but cant really understand how they work or how they should be adjusted. see pic Any help would be appreciated

That gadget has nothing to do w/your problem. How it works tho,is that your whole keyhead is on a pivot like the tremolo block on a Stratocaster. It only moves tiny fractions of an inch however. From the looks of your guitar it's probably hooked up to your so-called A,B & C pedals. Each pedal has a sub-linkage that pulls the head block ever so slightly away from it's stop - in effect sharping the whole guitar by a tiny,almost unmeasurable amount(no,not enough to break a string). Tune it like this: step on your A pedal while picking your E(4th)string and listen to hear if it goes ever so slightly flat when the B strings come up to C#,then adjust the tuning nut at the left end of your guitar - the one that's hooked up to your A pedal till the E string stays put when the pedal is depressed. Repeat for the other pedals involved using the strings that are not being pulled as your measuring stick.When they don't go flat when the pedals are employed,you have effectivly tuned out all cabinet drop and the guitar will play unbelievably in tune.
For your string breaking problem just use Jagwires. |

I have the same model guitar and had the same problem for a while until I figured a few things out. There is more tension on the 3rd string on these guitars than most any other and to keep the 3rd string on it you ned to do a few things before you string it up. Get Jagwire
11.5 strings! They are the only ones I've found that won't break. Burnish the top of the changer finger with a hard smooth piece of steel. I use a burnishing tool
which is a hardened piece of tool steel with a curved face and a wood handle. When you are putting the string on, put the ball end in, run the string through the hole in the finger, wrap the string around a wooden dowel and pull it up as tight as you can as you are tightening the allen head screw, the bring the string up to pitch slowly working the A pedal all the while to stretch the string as you are tightening it.
This works for me.
The tuners on the head end of the guitar are for tuning out cabinet drop and work great just as Michael described. Once you get the 3rd string problem behind you, I think you'll find this an amazingly well engineered and great sounding guitar. Mine has the best sustain on a steel that I've ever heard. |
