I'm just getting to realise that half the reason I keep on splitting top notes is my Besson 752 (the other half being my lip) and that I could actually benefit from a better instrument. Thus far, i am looking at Sovereigns, but have come accross this instrument. A lot of people keep saying that the 421 is very similar to the round badge B&H Sov, and they play very well. However I'm damned if I can find anything more on them. I live and work in London, and don't want to go too far to try one (in case I really don't get on) but don't want to buy one over the internet, as I know full well that each one will be different, and I want to find 'mine'. I have found First Brass in Northhampton that stocks them, but they appear to be more of a mail order operation. I have also found JP Brass in Somerset, but price appears to have gone up to £1,000, which is near enough second hand sov money, maybe a bit above. Any advice?
