Hi. I just got myself what seems to be an older Squier Vintage Modified Fretless Jazz. Serial no starts with IC06 which seems to tell that it (the neck, at least) was made in Indonesia at the Cort factory in 2006. Pickups are labeled Duncan Designed and they are nice sounding. Very nice neck with Ebonol fretboard with lines. I have a few questions: First: How do I check that it actually is a VM. According to various references the VM series was first introduced in 2007. Second: When I "board" a string close to a stripe marking the fret position there is a buzz when the string vibrates. So I suspect that the fretmarkers are not 100% flush with the fretboard. In order to correct that I think of wet grinding the board a bit to level it out. Have anyone here tried leveling an Ebonol board like that and what was the experience? Good or bad? Thanks for reading and replying.
