This problem applies to both my RGT220A with the Edge-Pro and my RG3120 with the Lo-Pro. The problem is similar to the one as in this post
http://www.jemsite.com/forums/showthread.php?t=69938 in the second paragraph.
When I am going from lower pitch string to an upper pitch string the lower resonates/vibrates enough to be picked up through the pick-ups. At first I thought it might be my thumb dragging across the lower pitch string so I changed my pick holding to avoid this. The problem persists.
I did a search of the Tech Forum because I remember having read a post awhile back with a member having the same issue and that is where I found that post. Alas there is no help there.
To test it I mute the D, G, B and E strings with my fingers and pluck the A with normal pressure with the tuner in my GT-6 fired up. When I mute the A string the tuner which read A for the string I hit it changes to E. With the tuner still reading E I touch the E string and no more E on the Tuner.
This tells me a few things and please correct me if I am wrong. I think the vibrations from the A string are vibrating the E and the same for whatever string I am plucking to the string above it.
I have tried many fixes from my search on the forums. I have stuffed the trem cavity with materials to kill any vibration there. I have raised my action. I have unlocked the nuts and switched them around. Stuffed Q-tips under the strings before and after the string-
retaining bar.
I am at a loss here. I cannot figure out what the problem is if there is any or is this just one of those things.
Thoughts or suggestions anyone?
