Installed a new set of Dunlop Super Bright’s on my Fodera and the G string has a phasing / out of tune sound on the high Ab and G. In 30 years this is the 1st time I’ve had this. Put another G on and it’s gone so must be the string ? I always do the right angle thing before cutting the string and have the right amount of winding on the post.
Worth asking for a refund / replacement set / string ?
