my p-bass has been feeling dry lately so i got a crazy idea in my head to drop a darkstar in! so i was wondering how hard it is to install one, what tools do you need, and is there any way to have it done for you?
Most competant luthiers can do the routing. It's fairly routine especially if they are guitar builders. I've heard of prices ranging from $25 to $50 per cavity. Here's the routing dimensions. Shop it around.
buy a DREMEL SET!!!! Be careful though. Make sure a pickguard could hide any mistakes and you do not want that tool getting out of hand on your finish...
