This summer I played a run of the Producers here in PG. Going through my saxophone collection I picked a Nobel Tsax to play the show on.
When it comes to playing in public I pick whatever will make me sound the best.
I picked it over the usual Yamaha sax that I use. At half the price the Nobel is the best buy around. The 3 main things I noticed with the Nobel were much better tone and tuning and really fast response for the technical passages. The sound is less edgy and blends really well with the other instruments. At less than $1400 one can buy an Alto sax ( less than $1000) and a Tenor Sax for the price of 1 Yamaha Tenor. I played the Sax hard for 2 months and other than making a slight adjustment of the 1/1 Bb adjustment screw it did not go even slightly out of align.
As a player switching back and forth to the Tenor from the Clarinet I appreciated it's lighter feel, less strain on the hands etc.
After most concerts I review what I did musically and technically. I use the concert recordings when I do this, they are an invaluable tool. I consider every aspect of my playing and setup. All areas that do not meet my ideal get worked on.
