I have owned the Jean Paul 400 and 600 trombones and they both are good horns that punch much higher in quality than the price point that they are sold at. These horns are exceptional values for the beginner and intermediate trombonists.
Furthermore, I must say that when you buy from The Jean Paul Company , you are dealing with a reputable company that stands behind their merchandise and is really concerned with customer satisfaction . Recently ,I had a problem with one of my horns and it was immediately corrected without any fuss by Tim Zenderman, their knowledgeable staff representative.
What more can I say? Now, I was able to quickly return to the more serious issues of orchestral trombone performance without being hindered by technical instrument problems.
The way The Jean Paul Company handled this matter demonstrated that it stands behind their warranty 100%.
