I've played hundreds of YTS-21s and YAS-23s and although they are pretty darn consistent, I have played many that were average, some that were not good sounding for whatever reason and a very few that were amazing.
Would that not depend on each individual horns set-up ?
I have not played hundreds of 21s ... tons of 23s 32s 52s and 62s but the 21 ...only 3 tenors ever.
About six years ago a friend and cyclist buddy of mine got ill and had to give up cycling. He later asked me if I thought it was a good idea for him to take up sax (at 60 ) So of course I said yes.
We searched eBay for a 23 but nothing in good shape came up. Then he called me and asked what a 21 was like because he had seen one for sale in fabulous condition for ÂŁ290. I gave him the nod and he not only bought it, but he gave it to our friend Griff for a roo-pad re-pad.
I played it after it came back and was intrigued at how pure the sound was ... it felt very classical.
I found myself wanting to have a go on it every time he came round...not that I haven't got some very beautiful kit, It was just a different sound pallet and kind of fun! I don't think I have ever felt like that about a 23 , not that the 23 isn't a great student horn, it is ! But it doesn't hold my interest like the 21.
On top of that, if a horn responds well and is incredibly well in tune ...is not the rest of it down to tonal colour and it's relationship with you and your mouthpiece ?
I am happy to own one and in time I will re-pad my one too.
I regard them as under priced and extremely underrated...and I will say it again, politely, There are many horns I have picked up and played over the past 15 or so years that cost lots more and would not perform as well.
