Did you top mount or through-bolt the new nut? I tried that option on my SLQX. The original holes and the ones on the R2 nut didn't line up, but they were too close together for me to just drill new ones without filling the old ones first. I was going to through-bolt mine, but didn't want to take the chance of chipping the finish on the back of the neck. So I just left it as is and sold it.

Thanks again FRG. Very cool that you've found a solution. Hopefully someone from Jackson will notice this and make an adjustment so these guitars won't have that issue in the future.

Mine plays just fine although I will change the pickups out!

I'm having the same issue with my SDX neck...

FloydRoseGuy, it's been a few months since you changed your nut, are you still happy with it ? Did it really solve the strings slipping issue after all ? Could you please tell us more about it ?

I posted a similar thread recently too.
Im trying to remain positive because I wanted this guitar so bad.
I wont sell it . I would like to fix it. It seems it might be a common issue.

Does Jackson care?

Would it be worth it to take it down to a guitar shop?

Deep breath.....................
