NP.
The JF34 A string might be a bit short though, it’s 35.5 scale and a far away tuner even on 5 string, slightly closer than on a 6er though.
I didn’t even had to cut my A, just fed it to the post as is and it gave me 4 wraps I think. Hope it works for you.
Email Jason at fretnation, he’s super friendly and knowledgeable and probably can correct the order it A will not fit.
Actually sec, I have a new JF34 A somewhere, I’ll measure it for you, brb.
I measured new uncut JF34070 - it should be fine and will reach bottom far post, and silk will be post nut, you are all set.
