I just picked up a Holton Collegiate tenor that someone didn't solder very well. I've never done any kind of soldering on an instrument but have done lots of copper sweating and electronics soldering. I'm going to strip and delacq this horn because of corrosion issues. Should I bother trying to fix the solder job myself or religate that to a pro? Also, what are my chances of finding a new neck, for this horn, the one it came with is quite sloppy and not orginal.
