The heavy in demand session-/performer playere use to have 2-3 saxes playing as close as possible to each other. 2-3 Keilwerths, 2-3 MkVI, 2-3 YTS 62 ..... which are set-up by the same tech. They are paid to take good care of thier saxes so they can "deliver".
This is interesting. We know that the top (and famous) players tend to have multiple horns - Sanborn had many. But was this for a practical reason ?
If we had the money (and the need ?):
would we:
1. try and find a horn that more or less played the same as our favoured horn;
- eg I know some mk6 players try and find instruments close in serial number to their main horn (as a spare);
2. have a few horns that are the "accepted great horns";
- like a 10m, Silversonic, SBA, Mk6 - (so that we can push our sound to the nth degree if we wanted to do a particular project and wanted as much period authenticity as possible)
3. just collect them like classic cars;
4. are they given to these top players - well yes, I think we know that to be true.
There are many accounts / album notes to say that an artist plays xx horn through sponsorship. We also know this to rather untrue much of the time - apart from the posed picture on the album cover.
We also know that people do change instruments from time to time - although this might apply more to mouthpieces and their wanting something of an easier blow as they get older, or maybe styles / fashion has changed too.
I think Sanborn played on a silver-plated Yamaha for a while didn't he ? It would be a feat to pick it out by ear though, and I think that mic choices / different studios / fashion for more / less compression / type of reverb will sound more like a change.
If he did play other horns for any period we can only presume that he did so because he felt / heard something different that he liked. This might only be perceived by him (maybe) - but it is something that I understand.
My mk 6 alto and my Woodstone Ishimori sound very alike when I play them, but they don't interact with me in the same way - so I'm led to play slightly differently on each. I do have a recording of a funky thing over the same backing track with the two horns, and I think I'm led to different places.
I could post them I guess, if anyone is interested. How would I post an mp3 ?
