Was there ever any resolution to this? I am getting the same type of ghost notes with alternate tunings. Was it fixed with 2.1?
FWIW - I am on 2.0 but never saved any settings or made changes through WB. Not sure if it came from the factory with 2.0 or if Sweetwater flashed it prior to selling it to me.
Due to life getting in the way, I am past the 30 day swap period, and I am just now getting to know the JTV-59P. Really like it so far but obviously would like to get this issue resolved.
