Is it possible to rout through a guitar that already has a finish on it without causing serious damage to the finish? For example, routing a control cavity, tone/volume holes, and switch holes? I am not going to try to do it myself (I have no chance of succeeding ), but should a pro be able to do it?
yeah, ive done it before, it will be fine.
I have done it before at work, but that was with a trusty manual next to me for reference.
