Oh, I see, I need it to replace the old one on MM JP6, which is worn (strings greatly deepened). Serial number of the guitar G41254. I'm not the first owner.
Thank you.
Yeah you have to be replacing one. I would imagine him calling AJ with the serial # will be sufficient, but as said they are 7 string nuts and must be trimmed.
Thank you for your advice and help. I found a dealer, who works with MM, and he agreed to bring the nut to my faraway country. At first i was worried that there is only for 7 strings, but as it turned out it is the only way.
