I like Monel lights on my '14 J35. It is strung with EJ19 Bluegrass strings right now, and they really bring out the low end. I have owned a J45, J45TV, AJ, and J15. The J35 is the best of the short scales. Pulling the pickup out and installing a new bone saddle made a big difference in tone in both my J15 and J35.
I just wish the J35 had wider nut, and subsequent string spacing. I will be selling it soon in the hope of finding a Fuller's J35 or J35 Collector's Edition.
