I had the bridge on my Vx700 changed to graphtech ghost saddles. I also recently had the entire circuit board replaced. I had a whiney background noise that the new circuit board seems to have fixed.

BUT I have a problem with my piezo saddles hearing their adjacent strings so that none of the pitch shifting works correctly because of noise from adjacent strings.

So to help figure this out I went into workbench and turned all the string volumes to zero. Then I brought up each string volume 1 by 1 and played all the guitar strings. The result was that basically all of my strings get varying amounts of input from adjacent strings except for the G string which is 100% discrete to the G string.

Never having tried this experiment before, I'm thinking that in a properly working variax all the strings should sound 100% discretely through their individual saddles and not bleed over into other saddles.

My question: Is this correct? What could be possible causes of this? could it be wired to the board incorrectly? Could it just be the saddles vibrating against each other?

Thanks in advance for any help.
