I haven't Dave, but I will. I gave it a good clean even though it was fresh out of the box, thinking there might be something getting in the way somewhere, but it was no better. Peter, I did play a lot better on the Magna – and that is not usually the case. I'll be happy to spend a good bit of my next lesson having my teacher look over the alignment, corks, springs etc. I did notice that the water key springs were pretty crook (on all the ones I played). You guys might be onto something. Thanks.
