I'm building a guitar RM GCSE and at the moment, the body is only 3cm thick. It's going to be a bolt-on neck and string-thru body. I think I should thicken it to 4cm but hoiw would I do this? Im planning to glue on an extra 1cm of wood on top but the only wood I have that thick is plywood, which kinda phails, as the rest of the body is mahogany. Help is much appreciated
ohai little sig.
