Hello Gentelmen,
Dave, that appears to be an old style (a favorite beer back in the day...). Max, also check out Hardy's Medium Scale in the FTC to get a good idea of the Signature in an Essence of current proportions. Please note that Hardy's bass has a custom ordered extended horn.
I did a mock up of the larger pickups in Tom's Dreaming found in a thread below. I ordered FatBoys, and there was no mention of any changes necessary. Conversations with Valentino lead me to belive the bass is in setup and final cure. Unfortunately Mica's been swamped so there hasn't been time for a FTC, but I'll post pics upon its arrival. You can also see FatBoys on an Essence sized body on Valentino's Coco/Ash Trip Omega Essnece in the Custom Bass showcase.
