AER AK15 - Guild GAD50 - Soucis

With any UST it always helps to very slightly round the edges and especially the ends of the saddle - helps to stop it binding in the slot. A couple of strokes with fine abrasive paper is all it needs. If you've still got the problem, then you need to pay attention to absolute flatness along the length of the saddle and its slot base. If the problem is still here, and you are sure these aspects are OK or taken care of, then it sometimes works to apply a few gentle file strokes to the saddle base just above the loud string. Some folks swear by putting vertical slots in the saddle for a few millimetres up from the base to help with balance problems, but I have no personal experience of that. Good luck!
