I have the opportunity to procure a set of Risers for my KG4's. Unfortunatly, they are in Oak Oil and not Walnut Oil. Has anyone ever successfully changed the Oak Oil finish to Walnut? I realize the grain is different, but its just the Risers so I'm not too concerned about the grain appearance. I'm not a wood worker, so I'd like to get an idea of just how much work this would be if it is indeed doable. Maybe I just need to be more patient and wait for a set Walnut Oil Risers to come available. I appreciate your input.
