Yes, the Freddie Green RT's are the only ones I've had problems with. For the moment, it's cured itself. It just comes and goes. Gigged last night with no problems. However, tomorrow may be different. I wish pgmusic would look into that, if enough problems are reported. Out of that long list of guitar RT's the "Green" tracks are the only ones I use, since I do a lot of swing jazz tunes.
