| This is an interesting question/idea that you have posted. I have noticed this difference between my two Bb's (same brand different models). I have a Bach Strad 43* and a Strad 37, both are the same,both standard setup (as far as the leadpipes and tuning slides are concerned) all the way down to the fact that they were both goldplated by Kanstul. If it weren't for the bell size and weight difference these horns would be identical. However it seems that the 43* really opens up in the high register. I can play (usable) range both higher and for longer on this horn, than on the 37. However it does not have the presence or the focus to the sound that the 37 has. I currently use my 37 for all of my playing because of the focus and the presence that it has both in a section and as a solo instrument, however I must work harder to play in the upper register. I find it amazing that such a seemingly small difference between the physical make up of two horns can make such a difference in playing characteristics. |
