I am a pro drummer/ pro carpenter. I have done some custom drum building as well as repair and re conditioning of some of my students drums. I have some vintage slingerland drums and a vintage Gretsch shell. I was wondering how much the worth is affected by installing new wrap (matching correct era colors and styles) and repairing defects such as holes that shouldn't be there. and the occasional split reinforcing ring. I was also wondering what the market would possibly be for vintage shells re wrapped or re finished and adding modern hardware. I have done this on a few occasions where the person liked the sound of the vintage shell and wanted to play the drum but didn't want to deal with the restrictions of the vintage hardware.
Please let me know your thoughts on these subjects.
