HiCouple of minor follow up suggestions to all the fine comments with Stay Brite solder and Flux.1. Be sure not to overheat the solder joint. If the Stay Brite Flux turns black it is too hot.2. If the solder is not flowing well then give it a small shot of additional flux, even while hot, and most of the time the solder will flow nicely.3. When done, and the joint is cooled off, give it a small shot from a small plastic bottle of Baking Soda and water solution to neutralize the acid.4. Then clean the joint in running water and it should be bright and shiney.For music wire solder joints I find that a propane torch is way too much heat. Most of the time I use a BENZOMATIC small handheld torch. Can control the area that is heated very well. For brazing using real silver solder a MAPP gas torch works well with white flux. Both from McMaster CARRJust some suggestions.Ray
