Hello
I have finally got hold of my dad's old beomaster. I have had it fixed by an technician, so it is also working now 😁
The only problem now is that it look tired. It has been stored in the attic between 20 and 30 years. So the wood case is dirty and faded.
Is it enough to use sandpaper and then some oil or is it to fragile for this treatment? The case is made of rosewood.
Hope you can help me in the right direction.
