I have just purchased on Craigslist a Pan American saxophone with the serial number 155211. This saxophone is in need of a full repad as it seems that all pads are original to the saxophone. This horn plays well yet is externally in very poor condition. Is it worth it just to have a repad or a full overhaul? If I were to get a full overhaul with repad what would be the value on this saxophone? I paid $50 for this sax so is it worth it to have a full overhaul?
