Comments about Bach 42A Stradivarius Trombone with Hagmann Valve:

I've just recently bought this trombone from a shop, they had about 4 of this model there so I spent 1.5 hours there trying out the products. What I found is that each of them are very different from each other, like hugely different, so i had the permission to take them apart and change the slide of this one to the other top and it really help me to find the perfect bone for me. The tone of the trombone ONCE I GOT USED TO IT is quite amazing, probably one of the warmest sound I'll ever get without practicing hard. But there's also a slight pressure that pushes back against the air stream, causing disturbance when holding loud notes, thus breath control is really needed. The weight of the trombone is balance almost perfectly. It did not gave me andy injuries while doing a 2 hours rehearsal, and the Hagmann valve was like a completely different piece of technology that makes alternate notes sound so real and smooth. Just small problems now: It's really quite hard to get loud notes without distorting the sound (i meant like ffff long notes) 1st position notes are never in tune with each other, Great stuffs: Smooth, majestical, warm sound (typical of Bach) Perfectly balanced slides (great) Truly great sounds can be achieve when the player get use to the instrument Do consider this trombone when you are shopping though, try it out, and ask them so that you are able to switch the parts around to achieve the best sounds, best slides,,,
