I have my 4080 JG at a shop being worked on due to a "high second fret" (the fret board is probably raised in that area due to a previous botched attempt at adjusting the rods by someone who didn't know what they were doing). The luthier left a voice mail yesterday (that T-Mobile finally let me access today
), and he said that he found that there is a piece of lead in the channel 
and wondered if this was a normal thing on this model. 
This is the first time I've heard anything like this. Anyone have a previous experience finding a counterweight?
