I am currently 3d modeling Ibanez ftm 33, and I have some questions that more experienced builders probably can help me with. I am planning to use edge III 8 string fixed bridge so how deep should be the cavity for installation or if someone has some roughing planes for that bridge it would be helpful, the second thing that I am not sure of is the thickness of neck portion that is above body plane, and what is usual fretboard thickness
