The sauce works great.Remember stirings will stretch at first so you will tune more often a few times.Most nuts are not slotted right so if the strings are binding take a very small thin file(they make files just for this) and slot the nut in a delicate manner!!! A pencil or graphite piece will work great for the nut.I use a pencil myself cause im an old fart but have wanted to try the nut sauce.................A graphtech nut will solve all!!!
