Knee lever not tuning.

Post by Nathan Burns »

Hi guys,

I feel like this must have been addressed somewhere on the forum, but I can't seem to word my search correctly to find a solution. Disclaimer I'm also not much of a mechanical mind so if this is a simple solution in front of my face, I apologize.

I have a good conditioned Mullen G2 that I bought used. I'm probably considered an intermediate level player so most of my playing to date has included use of my A,B,C pedals and my E raise and Lower knee levers on my left knee. While trying to find a melody line I was picking out I noticed I have a full step lower on my 6th string (G# down to F#). I also noticed is was quite out of tune with the F# being sharp and not dropping fully to where it needs to be. So I got my tuning wrench and tried to tune it but it won't effect the note at all. I tried going both ways (left and right) to see if I could get any movement either sharp OR flat and it won't work. However, it got to the point where I tightened it so much it effected the open string which I'm guessing is not a good sign so I losened it off, changed the nylon nut thinking maybe I had stripped it or something, but no luck. When I look underneath the steel I see the pull rod is moving when I engage the lever as it should.

Any one have any tips? Or is this something I may have to take into the shop for?

Thanks for your time.

I believe that you should back off on THIS screw (the split tuner).

Here's my guess as to what's going on. Your guitar is equipped with a split on the 6th string lower: it can be used in conjunction with the B-pedal to get a "G" note.

Since there are 3 possible notes using 6th lower and B-pedal raise, there are 3 tuning nuts. The third one in question -- the one you haven't mentioned -- is the allen screw at the end of the changer. UPDATE: I see Jon beat me to it. That's the screw you're looking for.

See page 8 of the owner's manual for the procedure to tuning a split. Pay attention to the order that you follow, since there are dependencies involved. I think this will solve your problem.
