I've been looking around for my first sax (alto) and I think I have decided the Kessler Custom is the one for me. Except one problem. Which one? I've been getting lessons 3 days a week for the past 2-3 months and I have decided to buy my own instead of renting out my teacher's awesome Yanagisawa. I want a saxophone that will have a mellower sound. So should I get the red copper or is it just not worth it?
