| Seinman,
The yellow brass bell model - TL6, and the rose brass bell model - TL6R are very, very similar, as far as blow characteristics are concerned. The major difference is the added warmth of sound, with the rose brass. The yellow brass may be a tad more responsive than the rose brass, but this factor is fairly negligible, for most players. The main difference is mostly noticeable in the mid and lower registers of the horn. Once again, it really boils down to individual taste, sound, and "feel" preferences.
Best always,
Bruce |
