Ok so I've been playing sax for around 5 months now and my old mouthpiece was a bit crappy and I thought I'd buy a better one. Yamaha being good for sax's I got one of their 4Cs.
Now I've been playing it a while and it seems to sound quite sharp and out of tune and I can't figure out why. It sounds worse than my old one. I'm not sure if it's the ligature not fitting properly or the cork or if it is generally just a worse mouthpiece. There is also the option I'm not used to it yet and haven't worn it in but it's not really much different to my old one.
