So the guitar I'm currently working on will have four layers on the body wings- 1" maple, 1/4" cherry, imbuya veneer, and etimoe veneer (in that order.) My idea- rout the basic control cavity into the maple, that plus the channels for pickup wires and bridge ground into the cherry, and nothing into the two veneers on top and use that to mount the pots/switches. Sound like it would work?
