If the horn is old and it looks brand new, look for stress/dent pulls. People will fix a trashed/bent up horn and relaquer it to somewhat cover up the work. Look around the neck strap hook, bow, and bell. If the horn has had major dent work/buffing, that compromises the structual integerty of the horn, which means it is weaker and goes out of adjustment easier. The horn cannot take the same wear and tear. Also, Compare the color of the neck to the horn. Sometimes the neck can be naturally, from the factory, a slightly different color than the horn. That is usually not the case. My question is, in terms of street value (not what it is worth as a players horn), how much is a relaquer mark 6 worth? I know people who would pay not a penny more than $500 for relaquer even if it played extremely well. Joshua Redman owns a relaquer SBA tenor. That horn is obviously worth something to Josh because its a players horn and he sounds good on it. Some people don't want realquers even if they do play well. Whats the deal? I know that the body can be weakend and stressed, but what else?
