I'm building a neck-through fretless, and I want to know people's opinions on the coordination of fingerboard thickness and bridge height? I will be building it such that from the nut to the bridge end of the body, the neck will be an entirely flat block of laminations (ie. no elevated portion under the fingerboard, like Spector do with their bolt ons). My bridge is still on its way, and I haven't started cutting wood, so I want to know what the general consensus is... Do I need a thick fretboard? Do I need to route out a cavity for the bridge to be recessed into?
