I sincerely doubt the
body shape or scale length on 1527's are drastically different from the 7620. So if anything it should fit pretty well as the only real change is the edge pro vs lo pro, and as
scale lengths are the same the space between everything should be fine.
I sincerely doubt that the body shape etc will have changed much, nor the scale length and thus distance between bridge and neck, and even if it has, it'll be easily correctable as having too much pickguard is better than too little.
tracing may be your best bet if you are unsure!
