It really depends on the condition of the horn and the quality of the relacquer. I've seen so many really bad relacquers, I would really be careful who I took the horn to. Typically, a relacquer will lower the value of a horn. I would not relacquer a horn unless it was a very ugly horn. In the case of my Conn 10M though, it had been sent to the Conn factory in Elkhart to be relacquered not long before my dad got it in 1963. He played it a couple years in high school, at college and in a couplt bands afterwards. I played it in jr. high, high school, college, and a couple bands also, and some of the lacquer was worn right off in places and the brass was starting to oxidize. It was an ugly horn! I wanted to give her back her good looks to go with her great sound! I shopped around and actually it took me 5 years before I found someone who I trusted enough to relacquer the horn. I was thinking about taking the horn to Elkhart to be relacquered. I found The Wind Works, and after seeing some of the horns that Luke had relacquered, I trusted him to do a good job. He has done a couple other horns for me since. I talked to another collector and showed him my sax. He said it was one of the best relacquers he had seen, and that only an experienced collector could even tell it had been relacquered! He felt that my sax was worth $1800-$2000. That's pretty good for a 1948 Conn 10M.
