The problem jumped from the 6th to the 5th string when I swapped the internal cables, therefore the problem is with the signal path on the internal electronics.

Here is the results from my testing: - I did try to reflash the 2.00 firmware as this seems to be the solution for several people. Unfortunately it did not remedy the issue - I swapped piezo pickup inputs with the 5th string. They feed separately into the control board so this was a very easy test. The noise moved to the 5th string (6th string became quite) which indicates that the piezos are fine. So this seems to be an issue with the internal electronics which I am not qualified to fix. That's a bummer because I will have to send it back for repair or replacement. I will let you guys know how it turns out.

I was able to isolate the noise to the low E string. Palm muting on the other strings produces no scraping noise. I adjusted the global volume of the low E string to -8.0 dB and that has reduced the noise, but it is still there. I am going to try some other experiments to see if I can isolate the noise further: 1. Swap the low E string output with another cable to see if it follows the string. This should tell me if it is isolated to the saddle or internal electronics. 2. Swap the low E and high E saddles. This should move the noisy saddle to a string that is not wrapped and should produce less noise. I will update this thread when I have results.

Thank you both for your replies. I will change the settings in Workbench to see if I can dial out that noise. If I have time I will make a recording to post on this thread. Rework, What did you adjust in workbench to fix the volume for your 11's? Was it a global volume decrease? If there is a compression being applied, that would explain why you can hear the pick attack noise more clearly. Thanks.

A little background on my setup. I have a dream rig consisting of a JTV-59, DT-25 combo amp, and POD HD500. I really like this setup and can dial in any number of usable sounds for our cover band, but I really miss a tremolo system. The JTV-89F seemed to be a perfect solution. I ordered one from the Dent n Scratch deals at Sweetwater and received a new JTV-89F on Friday. For the most part I really like the guitar. The neck is easy to play. It has a quality Floyd Rose, and I like the sound of the mag pickups. I can say for certain that the GraphTech Ghost piezo produces a fuller, wider sound; especially for the acoustic models. My only real gripe is palm muting when playing with distortion. The ghost piezo system seems to be much more sensitive than the one on my JTV-59. It picks up the mechanical noise of the pick scraping the low E string much more. I can hear the same high frequency sound on my JTV59, but the 89F is much louder. I can dial out some of this sound by adjusting the pick orientation to the strings and moving my hand further back. This high frequency mechanical noise is completely gone when using the mag pickups. My question is, how many of the JTV-89F owners are experiencing this? I also noticed a lot more digital noise when using any distortion sound with the modeling on the JTV-89F. It just seems to be picking up a lot more incidental contact with the body and knobs of the guitar. It's not noticeable when playing, but it's there when the guitar is quite. Again my JTV-59 does not exhibit this nearly as much. Of course I can use a noise gate to cut this out completely. Thank in advance for your input. ice9mike
