I was wondering why a repair (or replacement) couldn't be done. Do you mean at the moment the issue developed or is there no hope of ever replacing the cork? My guess is that electrical tape's linear elasticity would become a problem, as well as the adhesive bleeding. There are silicone tapes available at hardware stores (see features below), but I would guess that cork would be best. I'm speaking as one who has never encountered that problem or experimented, so I am happy to hear everyone's comments on the subject.the cork on the neck split and could,nt be repaired
At last. For me it's tube corks and shellack. Mouthpieces, reeds, ligatures, necks ...... are important. If you have problems up there, your problems will be even bigger down the tube. It's like a car. If don't have a good injection/carbureter your car will lose power. I think it's the same with a saxophone.A good cork will be shaped to a cylinder, vs a cone as results from wrapping tape on the neck tube. This allows one to easily adjust the mouthpiece to the proper position rather than fight increasing resistance to shove it further on the neck.
