Quick questions:
Did you use a standard 34" set (JF 34xx) or a combination? On a 37" ABZ5 I use a mix of super long scale and standard scale (JF36xx and JF34xx).
Any issues with the nut slots being too small? On my ABZ5 open E and A, with their relatively light gauge (0.072 and 0.096), tend to rattle in the nut slot (especially the A) and I would probably need to fill the nut to help with that.
Asking because I should be getting a Super J in the few coming months and I am wondering if I should perhaps ask for a custom nut for the TIs.
You’re best off with a custom set the G needs to be shorter ideally otherwise you end up winding the string onto the post and not just the silk. Fretnation sells them in that configuration for Dingwalls.
