  • Wow!

    By: ,

    I spent (my wife says "wasted") some time in John Packer's shop today-5 minutes drive/10 minutes walk away- trying out the new Rath R100 and R400. WOW!!! How does the man do it?
    The R400 was such a joy to play, open throughout the range-pedal F to super F and the response at all dynamics was exceptional. The slide and trigger action felt as if the horn had been played in for a few weeks but it was brand new! I was seriously comparing it to my Gen II 88H and I found it difficult to come to terms with the end results. The slide was much better than my Conn slide and it was better than the prototype Yamaha one I use on the 88H; the valve action was slicker and smoother than the Conn and I feel that it played better all round!
    My only criticism was that the yellow brass bell was not to my taste as I prefer the warmer sound of a red brass bell and, strangely, it is supplied without a mouthpiece. The thumb lever has an adjustable or removeable rest bar by the side. It did nothing for me but I can see that there are those out there who would like it.

    The R100 was a similarly interesting horn with a clarity of sound I have rarely found before. The way the notes just seemed to be there without the effort and stress normally accompanying the upper range from high Bb upwards. I was the first to try that trombone and once again, the slide was beautifully smooth. It is the perfect lead trombone.
    It was interesting to compare it to good used R10 which had just come into stock and is in the same price range. I could not decide which I would buy.

    Now I can't wait to try the R900 when it arrives.
