So I would not expect smaller body or different frets for that reason.Lukather's preference. The regular production signature guitars that EBMM makes are made the way the artists want them. In the first decade of the Petrucci guitars, if JP changed his preferred string gauge, the production guitars changed to match too. The LIII initially came with all-rosewood necks. After a couple of years, Luke's preference changed to roasted maple and the production of all LIIIs switched.
