If it turns out not to be the string, the problem is that too much of the string is contacting the finger now- most likely because the radius at the top of the finger has been flattened and needs to be restored. Typical solutions done without removing the finger include using 400 grit sand paper- wet/dry cut into short 1/4" strips and a bit of soapy water- done using a technique like a shoe shine rag over the top- being careful not to make it flatter- until the groove is gone- then buffing it out with a dremmel or whatever you have to polish/buff with. It needs to be stressed that the soap/water/aluminum grit can get down into the changer and axle when done this way and cause more problems than you have already so try to pack off the surrounding areas of the changer to minimize this and wipe the area clean frequently during the process. When done, use light oil to attempt to displace the debris left over and, in the future, you should consider adding a dop of oil on the changer finger and the roller where the string contacts it whenever you change strings to attempt to slow down this process. The safest way to repair it is to remove the finger from the changer, restore the radius, and then replace the finger on the changer. All of that being said, frequently simply a drop of light oil on the finger where the string is contacting it is enough to stop the sitar-like affect that you are hearing.[This message was edited by Jim Palenscar on 24 December 2006 at 08:00 AM.]
